Merry Christmas! I am a new learner of deal.II. Now, I want to use method of characteristic to solve coupled equations like those in step-21. However, I met a problem when I want to use VectorTools::point_value to get the value of saturation in arbitrary points. It showed "the finite element is not scalar."
There are two versions of this function: one where the solution is scalar and where you have a system of equations and therefore a vector-valued solution. You need to call the correct one of these functions.
If possible, could you send me some programs about using method of characteristic to solve equations for reference, especially coupled equations even better?
There are several tutorial programs for coupled systems. There is, however, no program for the method of characteristics.
