I have a set of 2d meshes that i read from .msh files. Each 2d mesh is z=const circle with exact number of nodes in each layer. Layers differ by the circle radius and the z-position. All the layers are coaxial and I need to merge them in a single 3d mesh. They have to be connected without generating additional intermediate nodes between layers. Mesh size inside each layer is much smaller than the z-distance between layers. Is there a simple way of doing that? Big thanks!
//Or maybe, if there is a way to generate such 3d mesh without preparing 2d layers beforehand, would be great.
It’s quite hard from your description for me to understand what you’d like to achieve.
To me this seems like a meshing question, and as you are using the msh format, it is likely that you can achieve this by using GMSH (https://gmsh.info/), either through their .geo format, or Python API.
