Hi R,
I tried debugging sfepy/terms/extmods/termsNavierStokes.c but could not locate the error.
Can you tell me when does sfepy raises a ccore error (I saw it in some .pyx and .c files)
Can you kindly send me the .vtk file generated by the script so that meanwhile I can run an analysis and add it to my mid term report.
Regards,
Ankit

the failing function is in sfepy/terms/extmods/termsNavierStokes.c - try
debugging it (printf...). I cannot reproduce it, sorry :]
