Model runs for analysis but not for optimization
Hello,
I try to run an optimization run (see file attached).
When running analysis it's okay, but when running optimization I have the message
The rotational displacement has large magnitude, -178164 degrees
At beginning of .out of optimization I have this information:
*** INFORMATION # 815
The total number of rigid elements, whose rotational dependent d.o.f.
are removed because there is no need to constrain those d.o.f., is 3.
I don't understand if my optimization error is coming from this automatic removal or from something else?
Thank you very much!
Stéphane.
