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.</div><div><br></div><div><img id="40b56310-96fa-4542-86b0-f9bdcfe5c383" height="947" width="947" apple-width="yes" apple-height="yes" src="cid:95ED17DE-9292-4341-B0D5-8DEE295FB837@ucolick.org"><br><div>
