Hi, I have two simple question : The first one is : Is it possible to integrate source terms to make them easier to calculate ?
Basically, I can write this : the function xi is my test function, and sigma is just an independant function. But will I be able to calculate it in my right hand side ? The expression of sigma is complicated and it is a derivativ of a numerical function solved in another part of the code. So if I have to calculate the gradient of sigma I would have to use second order derivativs of this function which is not good I believe. The second one is : do test function also have to respect the incompressibility equation ? I have two variables that verifies an incompressibility equation : Then, during my calculation of the weak part, I use a test function written And I have termes in and that appears in my weak form. Can I write to simplify my weak formulation ?
