Hi all,

I can't find anything in the manuals, any example in the demo directory and even google is silent like a grave, when asked for "anisotropy site:fenics.org".
Does it mean that anisotropy is not supported by FEniCS?

Can you be more specific on what you have in mind?
My question is, if anyone has already tried to solve any anisotropic 
problem with fenics?
One of the problems, which come to my mind is that for anisotropic 
material I need at tensor function for material property. Can FFC handle 
this?
Just define the equation you want to solve and try compiling it with 
FFC. For an anisotropic solid, part of this will involve defining the 
constitutive model. The DOLFIN library shouldn't need to be (nor should 
it be) aware of the details of the constitutive model.

Strange, this seams to be quite easy to develop. Or maybe just no one needed that feature so far.
