I am implementing a stabilized weak form of a vector-valued problem (e.g.,
displacement u and pressure p with corresponding weighting functions w and q).
One of the stabilization terms takes the form (grad q, \tau grad p), where
\tau is actually a tensor. Here \tau is locally determined by solving an
element-wise linear system. Therefore I am using a FullMatrix class for \tau.
However, since \tau is involved in the numerical integration, it seems more
convenient to convert \tau into a Tensor class.
Is there a quick method to convert a FullMatrix into a Tensor? Or is there a
better way to code this workflow? Any suggestion is appreciated. If more info
is needed, please let me know also.

I don't think there is an easy way short of just copying elements one by one.
Out of curiosity, what is the equation that defines tau, and why can't you
just write this equation in terms of tensors right away?
