ANSYS Mechanical - change convergence criteria

KeganLeckness · July 7, 2016, 18:06

Hi all,

How can you change the convergence criteria in ANSYS Mechanical?

If you monitor force convergence, for example, you can clearly see values like 2e-3 or 1e-8. How can you choose those values. The only options I see are under Tools > Options > Convergence > Target Change, but here, the default value is 20. I need to do a sensitivity analysis and change the convergence criteria from .001 to 1e-6, but cannot seem to do so.

Hi,

I defined a new material properties for my geometry in ansys mechanical v17 using "command" code. The problem is, the simulation terminated in the beginning with no error.
In ansys V15 I could do this with no problem while in V17 I can't.

I would be thankful if anyone can help me with this problem.
