Hello mohsen,

Your problem is with the term [(omega . a) - (a . omega)] in equation for "a". The return of this operation is a tensorField and not a symmTensorField. Then two options to overcome this problem:

1 - Find a manner to [(omega . a) - (a . omega)] give a symmTensor. I think this is not possible, but ...
2 - Work with tensorField type. Then, "a" need to be declared as tensor field, the fvMatriz for "a" equation and all the operations that use "a" also need be of tensorField type. See also that omega=skew(L) in OF.

Best regards,
Jovani
