I want to calculate a 3D Tensor which is build with the help of a trilinear form. I think that I can assemble this tensor with the help of Dolfin assemble.h The problem is that all examples in Dolfin (e.g. MassMatrix or StiffnessMatrix) are with matrices (assembled with the help of a bilinear form) and not with tensors (assembled with the help of trilinear forms). I think it must be possible to assemble a tensor instead a matrix because the definition in assemble.h is really general (there they use GenericTensor for the assembled A). So is there anybody who tried to program something similar or may be knows how I must declare A so that I can assemble it with help of assemple.h??? Thanks for your help Anne
