Just following up to see if anyone has any clue as to why UncoupledConstraintCorrection may not be working, or if there are any other collision methods I should try with the set up I have?

I have been using the SoftRobots plugin and followed an example which uses the ‘ShewchukPCGLinearSolver’, FreeMotionAnimationLoop’ and ‘GenericConstraintSolver’
I have three separate objects with their own DoFs that need to collide with each other. However, they are not colliding at all even with themselves it seems.

It was the MeshROI mesh that I re-exported.
So I just opened the original .step file in Gmsh and re-exported it as a .stl file again with the same settings as earlier.
At this point in time I still have no idea what caused it, but I will definitely update if I ever figure it out.
Thanks so much again!
Thank you so much for all the help, I definitely learnt new things from all of this.
Strangely, however, I just re-exported the mesh again from gmsh and its working now!
I didn’t change anything in the mesh settings, or the mesh itself, I just simply re-exported it (For the 4th time by the way) and it just happens to be working now.
Apologies for the confusion, I’ll place some images to help describe the issue

There are four chambers to be inflated with air in my design. Here are two images (Images 4 & 5) showing one of the chamber’s inner face. There are no red-square…[Read more]
My shape is made of tetrahedra yes.
I used MeshROI by creating a new surface mesh, which is 75% working. The 25% that isn’t working seems to be due to some stray constraint indices which aren’t visible on the mesh, or in the sofa scene when I view the triangles.
Any ideas why this could be happening?
Also does MeshROI only work…[Read more]
I am trying to inflate a shape using the SoftRobots plugin.
The inside of my model is soft and able to increase in volume in all directions, however I want to put an outer shell around it, so that it can only inflate inwards.
I tried using collisions, however that is having problems due to how close the walls are initially, so I’ve…[Read more]
