Problem about ALE

Recommended Posts

Hello everyone, my goal in this calculation is to make the depth of impact greater than 200 micros, and finally I've succeed by using ALE method (with ALE-Grid-Displacment).
But here comes the problem: After the impact, these two componant stick together (there's no friction between them). Which have not appeared in the Lagrangien method. And I'm wondering why, and how to avoid it?

Hi,

Can you try with a slightly higher value interface gap value?.

I tried with .005 and the results is as below.
