The easiest way is to press the PrtSc key on the keyboard and paste it on the drawing panel, so that the saving is static, and any software can do this. This is a screen capture method.

I don't have to bother to use the finite element software MD Patran. Avi animation video can be directly saved in post-processing, and animation can also be saved in proe motion simulation. The mechanical module has not been studied yet, but I think it should be able to save the animation.
