Trimesh dynamics gets very slow in meters

I am running physics for meshes. When using millimeter as the metrics, my frame rate reaches 60fps. But when I change them to meters, the number lowers down to 1fps or less. I am wondering if I did a wrong option. Figures below: Meter, slow: 7bb5a4e30dc9b618c5db72f0e263602c93efb346.gif Millimeter, f...

Re: Objects bounce away violently

Thanks for the reply.
I have replaced the bowl into a concave static trianglemeshshape
and replaced the boxes into convexhullshapes.
The results are as follows. The results are reasonable.

Re: Objects bounce away violently

Both are triangle meshes.
Is it because of concavity?
The big cyan container is concave.

Objects bounce away violently

I am using trimesh to simulate a bunch of small objects. Parameters are as follows: restitution 0, friction .2, lineardamping and angulardamping .3, ccdmotionthreshold 1e-7, sphereradius .5 collision margin 1e-6, I am using the space key to add new small objects. Sometimes, as is shown in the attach...
