hello all, i have to solve a nonlinear reaction diffusion equation. To not use a nonlinear solver I have to use a method in which every element have to know the gradient of the FE space in his nodes (i use Tet4 elements) and also know some parameter specific scalars. I have also to have the volume of the element (which i have already done)... How can I do it? How can make the element aware of the problem i am solving and of the value of the basis function on his nodes? Thank you, nelson
