switching from Fine5.3 to Fine 6.1

voyer arnaud

I had a project under Fine5.3 with a computation (let's say computation 1). I duplicated this project and started it under Fine6.1. Then I ran a new computation using "computation 1" as initial solution.

I made exactely the same thing under Fine5.3 and the convergence history is different. If using Fine5.3 there is a perfect continuity with "computation 1", there is no continuity under Fine6.1 and the amplitude of the oscillations I had increased!

I noticed some changes in the control_variables/expert_parameters. Some defaults values changed and there is new parameters like IRSMCH. These changes can be the cause of my troubles?

Thank U.
