[FLASH-USERS] Problem with applyBCEdge

[James Guillochon]

Hi all,

So I am using the Grid_applyBCEdge.F90 from the WindTunnel problem to include a fixed boundary condition in my simulation (-X boundary). It seems to partially work on the interface, but every other block doesn't seem to be applying the boundary condition, which results in a bizarre checkerboard pattern (attached to this e-mail). I think the issue must be in the looping indices in the region specialized function, which I have not modified. I am using FLASH 3.2, and the problem exists with the default ppm4 and ppm4dev. Any ideas? The attached image shows a slice through the grid cells just interior to the boundary cells.
