Hi all,

I am attempting to produce a mesh of a multi-body system. The surface remesh works, following which, the Tet mesher gives the following error:

Nobody in my immediate group of colleagues has seen this error before. Anyone who could suggest why this may occur?

No pierced faces, suspicious proximity, free or manifold edges are present in my split geometry (either root or remeshed)

Here's my approach: Import CAD -> Combine all parts -> Imprint all necessary faces & other surface repair -> Split by topology -> Create regions (individual fluid regions & multi-component solid regions) -> Mesh

disable the mesh model in all but one part/region and see if it works then do the same for each part to try to find the problem
