Killed during operation of calculix

Exactly. I don’t get why so many MPCs for comparately small element count. There must be something else too in addition to the expansion of the elements.
Maybe try a free-free modal extraction? See how many rigid body modes you get. Also can try a simple gravity load on a static step.

What do you mean? I don’t know what sense stands for

Any parameters of the original model should be relatively small, in my opinion, it should be because dozens of *restart,read leads to a lot of parameters accumulated, resulting in a lot of MCPs

Something that should be expected based on a deep understanding of the model. I mean, if after 2 restarts the MPC numbers grow, this is what should happen? And why? With the information available I wouldn’t expect that but I don’t know the details. So please check the output messages in the few first restarts. Right now I can’t provide better advice.

Can you try just with 1 restart and 1 read statement?

It may be easier to try to share the model if possible even if it is with dummy materials, loads, etc… To help debugging. Otherwise, there are too many variables for anyone to truly understand and debug the model appropriately.

What is the significance of this operation? What about my subsequent *restart,read?

share the model? what is the meaning of share the model? Can this action be used instead of *restart,read?
