I am solving an equation of type del.(c Del u)=0. The coefficient matrix is not static, and is dependent on the variable (non-lineal problem). The problem is setup in a way that the coefficient matrix is not available; however, the inverse of this matrix is available. The matrix is quite big, so I can not invert it by hand. Is there a way in which I can put the inverse matrix expression in COMSOL, and then invert it.
