Hi everyone,

I am performing a non-linear quasi-static analysis on a system made by elements with different materials and geometry. I attach the files.

The system has an SPC for dof 1, 2, 3 at the bottom part and compression pressure on the other 3 sides.

The problem is that the analysis does not converge because of error 4965. Is this a problem of the load pattern or load type, or a problem of analysis parameter setting?

 

Before this trial I performed on the same model a non-linear quasi-static analysis of simple tension along x axis imposing a displacement on the right side of the system and an SPC for dof 1, 2, 3 on the left side and the analysis converged. After this I imposed the displacement also along y axis, but it didn't converge, so I tried with forces, and then pressures, but the analysis didn't converge.

If the problem is the load setting, the definition of an envelope of the vertical loads with the horizontal loads could give good results?

 

Bests

Martina

    Can you also share the .out file of the run?

    Of course.

     

    Now I tried to add some other support to the element: the analysis is running. I will see if it converges when it will end.

    The symptoms associated with most convergence issues can be found in the *.out file.Please share the .out file of the run.
