Triremesh help

i have a mesh model here that i need to do some physics on. unfortunately it does not work, the mesh seems to be corrupt. tried a lot to fix it, without success. now i remembered there is triRemesh in rhino 7.
i dont have it yet and am quite in a hurry. so i cant use the demo.
could someone please give a try to remesh the attached model while keeping detail?
thanks in advance

Hi @brt1

There are a lot of problems with that mesh - holes, non manifold edges, self intersections.
TriRemesh or QuadRemesh alone generally won’t fix these - you’ll still usually need to do some other form of cleanup first.
Here I took an isosurface with Dendro then remeshed that:

thanks a lot for the meshes!
and the helpful explanations …
