Nvidia Flex soft body constraint type

When creating a soft body in Nvidia Flex using NvFlexExtCreateSoftFromMesh() which results in particles grouped together in clusters, which constraint type of Position-Based Dynamics will be used? Is it shape matching or general distance constraints or something else?

I appreciate any help.

According to this manual: https://docs.nvidia.com/gameworks/content/gameworkslibrary/physx/flex/manual.html, each cluster is held together with shape matching constraints. The soft body as a whole is held together by the fact that each particle can be a member of multiple clusters.

NvFlexExtCreateSoftFromMesh() also receives a float parameter called linkRadius. If you provide a linkRadius larger than particleSpacing, the function will additionally create springs (regular distance constraints) between the particles in the soft body.
