I am a beginner user of Ansys. I have a quastion about solving methods.
As we know there are various approach to the finite element method.
We can define our problem by minimalization of Potential energy or Complementary energy. This approach is called the “displacement”, other one “stiffness” method.

How can I chose the method of solving in Ansys?
