Hi, I am exploring the possibilities to use FreeFem to solve electromagnetic problem using the test date for coefficients. Specifically, I have test data for magnetic permeability /mu which depends on the solution. I searched other examples in FreeFEM but they all assume constant /mu. Does anyone try anything similar? Here is a simplified equation:
Curl( curl(A)/mu) =0
Where my is a table depending on absolute value of curl(A)
Thanks
