Fine mesh for KIVA3V
Using K3prep, I have been trying to refine one of the meshes of KIVA3V-Rel2 examples (4-Valve) by increasing the number of cells in X and Y directions. I simply increased the number of cells of each block (two times more than the original one) and then modified all the patching and reshaping statements of the iprep file, but there are many non-convex and inverted cells inside the computational domain which results in KIVA termination after few seconds of running. I can see coordinates of the non-convex cells in the otape11 file.
I would be grateful if someone could help me.
