Hi,
Can you please share the files (_0000.rad and h3d), so that we can review the same.

Hi @along_2006
Can you run NLSTAT with LGDISP?
Goto Control Cards>> PARAM>> LGDISP>> 1 to activate large displacement solution with NLSTAT and refer to NLPARAM in Loadstep>> NLPARAM(LGDISP)
You can add NLOUT for incremental results, FYI

The operation you said, I have set it, the deformation is still difficult to control. Can you see the model of my attachment? Try to modify and calculate, and then make a judgment
