I'm not sure how the smoothing works would this result in a (nearly) perfectly flush mesh between the two objects? I need the surfaces to line up for the type of contact analysis I would like to run.

It is not too complex. If you prefer to go for a hex mesh please keep consider that you will need time to get familiar with pyFormex scripts and that there is no ready-made solution.
One strategy is to voxelize the geometry, find the elements that are inside and outside the particle and save inside and outside elements as (voxel) meshes. After smoothing the border of each mesh you get 2 hex meshes.

I will not be able to share the STL openly but here is a screenshot of the current STL and the resultant Tet Mesh. It is a rather complicated geometry but a Hex mesh could help me with contact finite element problems.

It is possible to create 2 separated hex meshes using pyFormex. Can you share a screenshot with the STL?

I am looking to mesh an STL file using pyFormex. The problem includes trying to generate a 3D hexahedral element mesh for an embedded irregular particle in a matrix. This would effectively require two separate meshes for the matrix and the embeddded particle.

Is there a way to achieve this in pyFormex or to generate quad surface meshes from existing triangular suface meshes?
