Hello

Have you seen the TEDDY tutorials about moving springs?

TEDDY > File > Examples > ASE > english / deutsch > dynamics > a1_dynamic_overview

In addition you could have a look at the chapter 3.20 “SPRI - Spring Elements” in the manual SOFiMSHA.

Hi
Thanks for your Tips

I looked that example and chapter but i didn’t see anything about irregularities on the surface that spring moves.
