Hi. I'm new to opensees and I have a simple question.
We have a mesh generator based on bsp trees, so all the cells in the mesh are polyhedral. Is it possible to define a mesh using custom cells?
The problem seems to be with the element associated with the MeshRegion, since it doesn't seem to handle n-cells as elements... and each mesh region must have at least one element...
Can somebody help me?

Just miswrote... n-cells are n-dimensional cells, but we're in 3D.
Just substitute n-cell with:
polyhedral cells with N faces
So: not cubical cells, not simplicial cells...

are you asking if OpenSees can handle 'polyhedral cells with N faces' elements or are you asking if there are any existing elements in OpenSees that can be used to
create your model if your mesh generator outputs n-cells? .. if the question is the first then yes you can, if the second then no.

So I have to write everything on my own... starting from newElement probably...
Ok, thanks!
