Dear all, I'll like to manipulate with GMSH scalar fields calculated by means of Code_Aster. These fields are typically the principal stresses of a mechanical problem. I would like to calculate for example a linear combinaison of these fields or their product. I tried to use the Matheval plugging but, unfortunately, I did not success. Is it possible to compute linear combinaison of scalar fields and in that case, how? With my kind regards,
Jean-Phi
