Detailed Description

Class INSVCStaggeredPressureBcCoef is a concrete StokesBcCoefStrategy that is used to specify pressure boundary conditions for the staggered grid incompressible Navier-Stokes solver with variable coefficients.

This class interprets pure Dirichlet boundary conditions on the velocity as prescribed velocity boundary conditions, whereas pure Neumann boundary conditions are interpreted as prescribed traction (stress) boundary conditions. These are translated into Neumann and generalized Dirichlet boundary conditions, respectively, for the pressure.

Function to fill arrays of Robin boundary condition coefficients at a patch boundary.

Note: In the original SAMRAI::solv::RobinBcCoefStrategy interface, it was assumed that . In the new interface, and are independent.

See also: SAMRAI::solv::RobinBcCoefStrategy::setBcCoefs()

Parameters

acoef_data	Boundary coefficient data. The array will have been defined to include index range for corresponding to the boundary box bdry_box and appropriate for the alignment of the given variable. If this is a null pointer, then the calling function is not interested in a, and you can disregard it.
bcoef_data	Boundary coefficient data. This array is exactly like acoef_data, except that it is to be filled with the b coefficient.
gcoef_data	Boundary coefficient data. This array is exactly like acoef_data, except that it is to be filled with the g coefficient.
variable	Variable to set the coefficients for. If implemented for multiple variables, this parameter can be used to determine which variable's coefficients are being sought.
patch	Patch requiring bc coefficients.
bdry_box	Boundary box showing where on the boundary the coefficient data is needed.
fill_time	Solution time corresponding to filling, for use when coefficients are time-dependent.
