Hi, My current problem is that my 3d code gives a worst result with a grid 100*100*50 big than with a grid 100*50*50 big for exctly the same problem (laminar flow around a cube)

Any suggestions, comments or explanations would be welcome

(1). Re=1.o? Re=10.0? (2). Mesh arrangement between the two? (2). Plot results vs mesh size, and try to reach the mesh independent solution. (3). Two points can not extablish the trend. good luck.
