I have been at this assembly for a couple of weeks. I have turned off "Large displacement" and "Compute free body forces". I have turned on "Use soft spring to stabilize model".
Usually, I get a Large Displacement error, I click yes, and it gives me a displacement result, and I bond the displaced object. Now, I only get the "Numerical difficulties" error, and no Large Displacement error. What do I do now?
Thanks,
What I mean by it don't show it, is that there is a "warning" that there is a large displacement. When I ran the study before, same setup, the large displacement would show. But, this last time, nothing shows at all. The study runs and finishes, but doesn't give any results or warning or error, nothing.
it does not even giving results? "The study runs and finishes, but doesn't give any results or warning or error, nothing".
1st. Large displacement is not an error, it is a warning.
2nd. The reason that you do not see it again is its option has got checked in simulation properties. (please see the image below) Check that box off and it will appear again when you run the simulation and will let you to choose either to proceed with Small Displacement or Large Displacement.
The following documents provide you with further insight into large displacement.
