Hi Hannah,

I suggest you model the braid fibers using Line bodies.  Those can then be meshed with Beam elements and that is massively more efficient with nodes than meshing with solid elements. The corrugated material is thin walled so you should convert that to a surface model and mesh that with shell elements.

With the efficiencies of those types of elements, you can model a full diameter (or at least a half diameter) which you would want to simulate a simple bend in the pipe.

Does the braid just sit on the outside of the corrugated pipe or is there a solid filler (matrix) that holds the braids in place?  That would complicate things.

In the current version of Ansys Structural the node or element limit for the Student license is 128,000.
