Question: is it possible that the box generator generates a patch which does not touch physical boundaries but has ghost cells out of physical boundaries?

My application needs special treatment when ghost cells out of the physical boundary are used in calculating the fluxes, and for this reason I need to know whether a patch...

Hello, in algs/MethodOfLineIntegrator.C:Line252, the ghost cells at the level ln are filled by the patch data in the coarser level ln-1, but the patch date at that coarser level has...

I was using SGI MPI and MPI_Attr_get cannot retrive MPI_TAG_UB for communicator except MPI_COMM_WORLD, as documented in BergerRigoutsos.C:967. The if statement at Line 978, 987 is to ensure that attribute...

If it is not a restart case, TimeRefinementIntegrator::initializeHierarchy will call PatchHierarchy::makeCoarsestLevel and then call adjustMultiblockPatchLevelBoundaries at the coarsest level, and Patch will have correct PatchGeometry in all following simulations. In...

the BoxId of sing_box is not set before it is pushed to BaseGridGeometry::d_singularity (hier/BaseGridGeometry.C:2152 and 2223). It will not have negative effect until you want to restart. Box of of...

in SAMRAI/mesh/BergerRigoutsos.cpp, BergerRigoutsos::setupMPIDependentData(), one should check the value of flag instead of the returned attribute value pointer tag_upper_bound_ptr to determine whether MPI_Attr_get succeeds. This should be a typo. If it...

My code uses SAMRAI which is compiled with umpire and RAJA, although my code itself does not use Umpire or RAJA. In order for my code to compile, I have...
