void IBAMR::IBInterpolantMethod::getFromRestart ( )

private

registerIBHierarchyIntegrator()

virtual void IBAMR::IBStrategy::registerIBHierarchyIntegrator ( IBHierarchyIntegrator *  ib_solver )

virtualinherited

Register the IBHierarchyIntegrator object that is using this strategy class.

Reimplemented in IBAMR::IBLevelSetMethod, and IBAMR::IBStrategySet.

inactivateLagrangianStructure()

virtual void IBAMR::IBStrategy::inactivateLagrangianStructure ( int  structure_number = 0, int  level_number = std::numeric_limits< int >::max()  )

virtualinherited

Inactivate a structure or part. Such a structure will be ignored by FSI calculations: i.e., it will have its velocity set to zero and no forces will be spread from the structure to the Eulerian grid.

Parameters

[in]	structure_number	Number of the structure/part.
[in]	level_number	Level on which the structure lives. For some inheriting classes (e.g., IBAMR::IBMethod) the structure number alone is not enough to establish uniqueness. The default value is interpreted as the finest level in the patch hierarchy.

Note

This method should be implemented by inheriting classes for which the notion of activating and inactivating a structure 'owned' by this class makes sense (for example, IBAMR::IBStrategySet does not directly own any structures, but IBAMR::IBMethod and IBAMR::IBFEMethod both do). The default implementation unconditionally aborts the program.

Reimplemented in IBAMR::IBFEMethod, and IBAMR::IBMethod.

activateLagrangianStructure()

virtual void IBAMR::IBStrategy::activateLagrangianStructure ( int  structure_number = 0, int  level_number = std::numeric_limits< int >::max()  )

virtualinherited

Activate a previously inactivated structure or part to be used again in FSI calculations.

Parameters

[in]	structure_number	Number of the structure/part.
[in]	level_number	Level on which the structure lives. For some inheriting classes (e.g., IBAMR::IBMethod) the structure number alone is not enough to establish uniqueness. The default value is interpreted as the finest level in the patch hierarchy.

Note

This method should be implemented by inheriting classes for which the notion of activating and inactivating a structure 'owned' by this class makes sense (for example, IBAMR::IBStrategySet does not directly own any structures, but IBAMR::IBMethod and IBAMR::IBFEMethod both do). The default implementation unconditionally aborts the program.

Reimplemented in IBAMR::IBFEMethod, and IBAMR::IBMethod.

getLagrangianStructureIsActivated()

virtual bool IBAMR::IBStrategy::getLagrangianStructureIsActivated ( int  structure_number = 0, int  level_number = std::numeric_limits< int >::max()  ) const

virtualinherited

Determine whether or not the given structure or part is currently activated.

Parameters

[in]	structure_number	Number of the structure/part.
[in]	level_number	Level on which the structure lives. For some inheriting classes (e.g., IBAMR::IBMethod) the structure number alone is not enough to establish uniqueness. The default value is interpreted as the finest level in the patch hierarchy.

Note

This method should be implemented by inheriting classes for which the notion of activating and inactivating a structure 'owned' by this class makes sense (for example, IBAMR::IBStrategySet does not directly own any structures, but IBAMR::IBMethod and IBAMR::IBFEMethod both do). The default implementation unconditionally aborts the program.

Reimplemented in IBAMR::IBFEMethod, and IBAMR::IBMethod.

getMaxPointDisplacement()

virtual double IBAMR::IBStrategy::getMaxPointDisplacement ( ) const

virtualinherited

Get the ratio of the maximum point displacement of all the structures owned by the current class to the cell width of the grid level on which the structure is assigned. This value is useful for determining if the Eulerian patch hierarchy needs to be regridded.

Note

The process of regridding is distinct, for some IBStrategy objects (like IBFEMethod), from forming (or reforming) the association between Lagrangian structures and patches. In particular, this function computes the distance between the current position of the structure and the structure at the point of the last regrid, which may not be the same point at which we last rebuilt the structure-to-patch mappings. The reassociation check should be implemented in postprocessIntegrateData().

Reimplemented in IBAMR::IBFEMethod, and IBAMR::IBStrategySet.

initializeLevelData() [2/2]

virtual void SAMRAI::mesh::StandardTagAndInitStrategy< DIM >::initializeLevelData ( const tbox::Pointer< hier::BasePatchHierarchy< DIM > >  hierarchy, const int  level_number, const double  init_data_time, const bool  can_be_refined, const bool  initial_time, const tbox::Pointer< hier::BasePatchLevel< DIM > >  old_level = tbox::Pointer< hier::BasePatchLevel<DIM> >(NULL), const bool  allocate_data = true  )

pure virtualinherited

Initialize data on a new level after it is inserted into an AMR patch hierarchy by the gridding algorithm. The level number indicates that of the new level.

Generally, when data is set, it is interpolated from coarser levels in the hierarchy. If the old level pointer in the argument list is non-null, then data is copied from the old level to the new level on regions of intersection between those levels before interpolation occurs. In this case, the level number must match that of the old level. The specific operations that occur when initializing level data are determined by the particular solution methods in use; i.e., in the subclass of this abstract base class.

The boolean argument initial_time indicates whether the level is being introduced for the first time (i.e., at initialization time), or after some regrid process during the calculation beyond the initial hierarchy construction. This information is provided since the initialization of the data may be different in each of those circumstances. The can_be_refined boolean argument indicates whether the level is the finest allowable level in the hierarchy.

resetHierarchyConfiguration() [2/2]

virtual void SAMRAI::mesh::StandardTagAndInitStrategy< DIM >::resetHierarchyConfiguration ( const tbox::Pointer< hier::BasePatchHierarchy< DIM > >  hierarchy, const int  coarsest_level, const int  finest_level  )

pure virtualinherited

After hierarchy levels have changed and data has been initialized on the new levels, this routine can be used to reset any information needed by the solution method that is particular to the hierarchy configuration. For example, the solution procedure may cache communication schedules to amortize the cost of data movement on the AMR patch hierarchy. This function will be called by the gridding algorithm after the initialization occurs so that the algorithm-specific subclass can reset such things. Also, if the solution method must make the solution consistent across multiple levels after the hierarchy is changed, this process may be invoked by this routine. Of course the details of these processes are determined by the particular solution methods in use.

The level number arguments indicate the coarsest and finest levels in the current hierarchy configuration that have changed. It should be assumed that all intermediate levels have changed as well.

applyGradientDetector() [2/2]

virtual void SAMRAI::mesh::StandardTagAndInitStrategy< DIM >::applyGradientDetector ( const tbox::Pointer< hier::BasePatchHierarchy< DIM > >  hierarchy, const int  level_number, const double  error_data_time, const int  tag_index, const bool  initial_time, const bool  uses_richardson_extrapolation_too  )

virtualinherited

Set integer tags to "one" in cells where refinement of the given level should occur according to some user-supplied gradient criteria. The double time argument is the regrid time. The integer "tag_index" argument is the patch descriptor index of the cell-centered integer tag array on each patch in the hierarchy. The boolean argument initial_time indicates whether the level is being subject to refinement at the initial simulation time. If it is false, then the error estimation process is being invoked at some later time after the AMR hierarchy was initially constructed. Typically, this information is passed to the user's patch tagging routines since the error estimator or gradient detector may be different in each case.

The boolean uses_richardson_extrapolation_too is true when Richardson extrapolation error estimation is used in addition to the gradient detector, and false otherwise. This argument helps the user to manage multiple regridding criteria.

This routine is only when gradient detector is being used. It is virtual with an empty implementation here (rather than pure virtual) so that users are not required to provide an implementation when the function is not needed.

protectedinherited

Register a state variable with the integrator. When a refine operator is specified, the data for the variable are automatically maintained as the patch hierarchy evolves.

All state variables are registered with three contexts: current, new, and scratch. The current context of a state variable is maintained from time step to time step and, if the necessary coarsen and refine operators are specified, as the patch hierarchy evolves.

registerVariable() [2/2]

void IBAMR::IBStrategy::registerVariable ( int &  idx, SAMRAI::tbox::Pointer< SAMRAI::hier::Variable< NDIM > >  variable, const SAMRAI::hier::IntVector< NDIM > &  ghosts = SAMRAI::hier::IntVector< NDIM >(0), SAMRAI::tbox::Pointer< SAMRAI::hier::VariableContext >  ctx = SAMRAI::tbox::Pointer< SAMRAI::hier::VariableContext >(nullptr), const bool  register_for_restart = true  )

protectedinherited

getLevelDt()

virtual double SAMRAI::mesh::StandardTagAndInitStrategy< DIM >::getLevelDt ( const tbox::Pointer< hier::BasePatchLevel< DIM > >  level, const double  dt_time, const bool  initial_time  )

virtualinherited

Determine time increment to advance data on level. The recompute_dt option specifies whether to compute the timestep using the current level data or to return the value stored by the time integrator. The default true setting means the timestep will be computed if no value is supplied.

This routine is only when Richardson extrapolation is being used. It is virtual with an empty implementation here (rather than pure virtual) so that users are not required to provide an implementation when the function is not needed.

advanceLevel()

virtual double SAMRAI::mesh::StandardTagAndInitStrategy< DIM >::advanceLevel ( const tbox::Pointer< hier::BasePatchLevel< DIM > >  level, const tbox::Pointer< hier::BasePatchHierarchy< DIM > >  hierarchy, const double  current_time, const double  new_time, const bool  first_step, const bool  last_step, const bool  regrid_advance = false  )

virtualinherited

Advance data on all patches on specified patch level from current time (current_time) to new time (new_time). This routine is called only during time-dependent regridding procedures, such as Richardson extrapolation. It is virtual with an empty implementation here (rather than pure virtual) so that users are not required to provide an implementation when the function is not needed. The boolean arguments are used to determine the state of the algorithm and the data when the advance routine is called. Note that this advance function is also used during normal time integration steps.

When this function is called, the level data required to begin the advance must be allocated and be defined appropriately. Typically, this is equivalent to what is needed to initialize a new level after regridding. Upon exiting this routine, both current and new data may exist on the level. This data is needed until level synchronization occurs, in general. Current and new data may be reset by calling the member function resetTimeDependentData().

This routine is called from two different points within the Richardson exptrapolation process: to advance a temporary level that is coarser than the hierarchy level on which error estimation is performed, and to advance the hierarchy level itself. In the first case, the values of the boolean flags are:

• first_step = true.
• last_step = true.
• regrid_advance = true.

In the second case, the values of the boolean flags are:

• first_step (when regridding during time integration sequence) = true when the level is not coarsest level to synchronize immediately before the regridding process; else, false. (when generating initial hierarchy construction) = true, even though there may be multiple advance steps.
• last_step = true when the advance is the last in the Richardson extrapolation step sequence; else false.
• regrid_advance = true.

resetTimeDependentData()

virtual void SAMRAI::mesh::StandardTagAndInitStrategy< DIM >::resetTimeDependentData ( const tbox::Pointer< hier::BasePatchLevel< DIM > >  level, const double  new_time, const bool  can_be_refined  )

virtualinherited

Reset time-dependent data storage for the specified patch level.

This routine only applies when Richardson extrapolation is being used. It is virtual with an empty implementation here (rather than pure virtual) so that users are not required to provide an implementation when the function is not needed.

resetDataToPreadvanceState()

virtual void SAMRAI::mesh::StandardTagAndInitStrategy< DIM >::resetDataToPreadvanceState ( const tbox::Pointer< hier::BasePatchLevel< DIM > >  level )

virtualinherited

Reset data on the patch level by destroying all patch data other than that which is needed to initialize the solution on that level. In other words, this is the data needed to begin a time integration step on the level.

This routine is only when Richardson extrapolation is being used. It is virtual with an empty implementation here (rather than pure virtual) so that users are not required to provide an implementation when the function is not needed.

applyRichardsonExtrapolation()

virtual void SAMRAI::mesh::StandardTagAndInitStrategy< DIM >::applyRichardsonExtrapolation ( const tbox::Pointer< hier::PatchLevel< DIM > >  level, const double  error_data_time, const int  tag_index, const double  deltat, const int  error_coarsen_ratio, const bool  initial_time, const bool  uses_gradient_detector_too  )

virtualinherited

Set integer tags to "one" in cells where refinement of the given level should occur according to some user-supplied Richardson extrapolation criteria. The "error_data_time" argument is the regrid time. The "deltat" argument is the time increment to advance the solution on the level to be refined. Note that that level is finer than the level in the argument list, in general. The ratio between the argument level and the actual hierarchy level is given by the integer "coarsen ratio".

The integer "tag_index" argument is the patch descriptor index of the cell-centered integer tag array on each patch in the hierarchy.

The boolean argument initial_time indicates whether the level is being subject to refinement at the initial simulation time. If it is false, then the error estimation process is being invoked at some later time after the AMR hierarchy was initially constructed. Typically, this information is passed to the user's patch tagging routines since the application of the Richardson extrapolation process may be different in each case.

The boolean uses_gradient_detector_too is true when a gradient detector procedure is used in addition to Richardson extrapolation, and false otherwise. This argument helps the user to manage multiple regridding criteria.

This routine is only when Richardson extrapolation is being used. It is virtual with an empty implementation here (rather than pure virtual) so that users are not required to provide an implementation when the function is not needed.

coarsenDataForRichardsonExtrapolation()

virtual void SAMRAI::mesh::StandardTagAndInitStrategy< DIM >::coarsenDataForRichardsonExtrapolation ( const tbox::Pointer< hier::PatchHierarchy< DIM > >  hierarchy, const int  level_number, const tbox::Pointer< hier::PatchLevel< DIM > >  coarser_level, const double  coarsen_data_time, const bool  before_advance  )

virtualinherited

Coarsen solution data from level to coarse_level for Richardson extrapolation. Note that this routine will be called twice during the Richardson extrapolation error estimation process, once to set data on the coarser level and once to coarsen data from after advancing the fine level. The init_coarse_level boolean argument indicates whether data is set on the coarse level by coarsening the "old" time level solution or by coarsening the "new" solution on the fine level (i.e., after it has been advanced).

This routine is only when Richardson extrapolation is being used. It is virtual with an empty implementation here (rather than pure virtual) so that users are not required to provide an implementation when the function is not needed.
