Question

Why is it not possible to change the solving method for the equation system of my model?

Answer

Basically, there are six methods available for solving the nonlinear algebraic system of equations. If your model does not include any nonlinearities (that is, you have created a purely linear system), the access of this selection field is blocked.

As soon as you define a nonlinearity in the model, the selection field for the solving methods is activated, and you can select the desired solving method.
