1. When I import my initial .x_t file, I generate a coarse mesh for it. The mesh below has 3mm large elements
Any advice?
The red X above Volume only deletes the Volume mesh - leaving the surface mesh alone. Thus when you mesh again with different parameters, the surface mesh does not change. You can see the interior mesh changes using the Section Cuts from the view control panels (lower left of display window).
If you want to remesh surface and volume, which would typically be the case, use the red X above Surface - this deletes both surface mesh and volume mesh.
When I meshed the model, I didn't use "surface mesh", and I only used a "volume mesh". For that reason, I'd expect that the "volume mesh", when it gets re-meshed, wouldn't be "hiding behind" any surface, and that I should see the change apparently, right? What is the correct behavior for this software? I would expect that when you generate a new mesh, it would display immediately upon completion, superceding whatever mesh you previously had, right? Do I need to click on something else to get the new mesh to display?
The Volume Mesh tool creates both the surface mesh and volume mesh. If any surfaces are meshed separately - so surface mesh exists - those surfaces are not re-meshed, and that existing surface mesh is used during the volume meshing process. Any surfaces that do not already have mesh are also meshed as part of the volume mesh process. (Surface mesh must be complete before the volume mesh is generated.)
If you do not delete the surface mesh before going through the Volume mesh generation process, that surface mesh is re-used - and that is what you see upon completion of the meshing process.
If you intend to change the surface mesh size along with the volume mesh size (which is often the case) you need to delete the existing surface mesh - which also deletes the volume mesh.

Hello, this answer was helpful. The fact that the surface mesh is created automatically when the volume mesh is created was an important note for me. Furthermore, figuring out how to remove the surface mesh that was automatically generated was something I had to hunt around for. For posterity, one must hover over the 2nd surface mesh button and volume mesh button to see the "X" that appears:
Correct - good point. Several of the tool icons in the various ribbons are multi-functional. The other sub-icons don't appear until the mouse is placed over/onto the tool.
