*** INTERNAL PROGRAMMING ERROR # 261 ***
Hi, I'm trying to do a linear buckling analysis with a 2D shell element. I don't know why, sometimes the analysis runs with no problems (right now, I tried to do it with an element size of 25mm and it gave no problems), but when I try to minimize the element size it gives me the next error
*** INTERNAL PROGRAMMING ERROR # 261 ***

**** ABORTING RUN DUE TO AN INTERNAL ERROR ****
I'll attach 2 models, one with 25mm element size, where the analysis it's alright, and another with 15mm element size, where I get the error

Altair EmployeeSorry @Premanand Suryavanshi, I didn't receive the notification of your answer and I only went to my posts now. I don't really remember how I solved the problem, but I was able to run the analysis somehow. Thanks for the help anyway!
Hi Pedro Neves,
I'm able to run 15mm model but i was getting error while running 25mm model. Then, I re-applied the constrain and load. Now it works fine.
Please try the same.
Thank you
