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

Frequently Asked Questions (FAQ)
- When defining my material, I get Warning No. 1136 and cannot continue working. How can I prevent this warning?
- How can I additionally model welds for the connection of two surfaces with a contact solid?
- I would like to use surface releases to model a bolt connection, which can only absorb compressive stresses from the support. Unfortunately, I cannot do this because my model is always unstable. Is there a model as a template?
- Why is it not possible to change the solving method for the equation system of my model?
- How can I incrementally apply the load of a load case to the model?
- After importing an .stp file, my model is unstable. What can be the reason for this?
- When entering a new material using the Diagram definition type, the first row is locked. How can I define the material?
- Are the models and presentations from Info Day 2017 freely available, and can you send them to me?
- Can I define nonlinear supports by using tables?
- Where can I find the RF‑CONCRETE NL add-on module? How can I activate it?
