Procedure:

1. Challenge 01

The given geometry was imported to HM using Import geometry tool. The geometry contain two components. Before creating the mesh, the geometry is edited using quick edit tools. Some of the edges of the model got suppressed using toggle edge option. (since at those egdes the mesh won't satisfy the minimum mesh size). After geometry editing, 2D mesh, with tria elements is applied to the surface using Automesh tool in the 2D panel. After applying the 2D mesh, 3D mesh parameters are assingned to the tetramesh parameters. Then tetra mesh is applied to the geometry. This method is repeated for the second component in the model.

2. Challenge 02

The given geometry is uploaded to the HM. After that unwanted edges in the geometry is deactivated using toggle edge option in the quick edit tool. After geometry editing, 2D mesh with tetra elements. After 2D mesh, tet collapse value of 0.15 is applied in the tetramesh parameters. Tetramesh applied to the geometry using selected 2D elements.

2. Challenge 03

The given HM file opened. There are 4 somponets in the file. All of these components contained a middle surface which splited the geometries in half. So before applying the mesh, these instesecting surface needs to be removed. So first, the half of the geometry gets masked to see the intersecting surface. After that the surface deleted using delete tool. This step is repeated for all the components. After that already created mesh on the componets got deleted so that new tetra mesh cold applied in the sam method as that of previous two challenges.

Result:

Following images shows the geometries after finising the mesh.
