Detailed Description

Class INSIntermediateVelocityBcCoef is a concrete SAMRAI::solv::RobinBcCoefStrategy that is used to specify boundary conditions for the projection Poisson problem embedded in a projection method or in a block preconditioner for the incompressible Navier-Stokes equations.

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

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.
