Shrink wrapping algorithms to make a mesh watertight for 3d printing

I'm investigating algorithms to make a mesh watertight for 3d printing. I'd be very excited to implement such algorithms. The initial input is a mesh which is not watertight and I want to understand and implement algorithms to transform it to make…

Where to find CAD and mesh models for tests?

I often find in the literature some numerical tests use CAD and mesh models. I also want to reproduce their results or test my algorithms on those models. But I am not trained to use CAD or mesh tools. I tried to get cad models from CAD website such…

How to efficiently get mesh cell/face connectivity?

If I have 3 lists: points, faces and cells that represents a mesh, where: points is a list of x,y,z coordinates, for example [-0.05, -0.05, 0. ], [-0.05, 0.05, 0. ], [ 0.05, -0.05, 0. ], ... faces is a list of list of points, where…

Meshing: Handle an internal boundary

I ask this question because I do not see (m)any examples and I'd like to avoid to spend hours or days to work into a mesher only to see that it is impossible: Consider the sketch below. As you see, I have a box with a mesh. Inside this box, there's…

Packages can help to refine parallel mesh and optimize parallel mesh

I have a parallel code. The code is implemented using MPI. I want to find a package that can help to implement global mesh refine and optimize meshes (avoid very thin element). The mesh in my work is all organized by triangle or tetrahedra. Do you…
