Hello, please, can you give me advise what can be wrong in this project? I’m not able to run the simulation.
If I compared other projects here, I can’t see where is the mistake. Thank you 
It is tube structure under load of forces and moment. There are 4 flanges. The flanges are fixed.
Whole project is here:
Thank you for your help.
Hey there, and thanks for using the forum!
I can see that you have a successful run, were you able to solve the error? Could you please share what you did with us?
Hey,
yes I had successful run but it didn’t cover all demanded loads.
I switched undeformable remote force to deformable and than the simulation started with no problem.
But when I added additional remote force, it crashed again. So I did some other improvements and I will see if it will work.
