Preserve Partial Mesh Under Translation/Rotation
Dear gmsh developers/users,
First off, I just wanted to say 'thank you' to all of the contributors to gmsh. It is a really amazingly useful tool!
What I seek is to run a sequence of simulations where some of the volumes move relative to a bounding volume. For example, the simplest case could be a single volume moving inside of a bounding box (Please see the attached images).
What is important for these simulations is that the relative position of the mesh nodes and the indeces of the mesh elements for the moving volume(s) do not change under translation or rotation. The mesh of the volumes that are not being transformed is free to adapt to the translated/rotated mesh elements.
(It may be worth noting that I am starting with .stp files as opposed to creating the geometry in gmsh.)
I have a tried a number of different approaches but have not been able to find the right spell to cast yet. I am hoping one you gmsh wizards can help me :)
Any ideas as to how to accomplish this?
