Mesh penetration problem in SOFA soft body simulation

[yangwxb]

Dear ones, I was simulating a hose device inserted into another mesh model and colliding at the edges of the model (hoses are rigid models), but the end result is that mesh penetration problems can easily occur. Do you have any good suggestions?

Hi @yangwxb

To be able to help we would need either a simple scene file highlighting the problem or at least a visualization of the collision models +detection ouputs. Best both. Cheers

Hi, @hugtalbot
Here is my scene file. The video in the title shows the runtime effect of importing the scene file into Unity. The model has undergone some adjustments, and the main issue now is that mesh penetration problems can easily occur.I want the instrument to interact with the grid model after entering the model, and it is difficult to penetrate the model.

Hello ! For me it seems that your alarm distance is too small with respect to your contact distance. Try increasing the alarm distance.
