To make my monocoque model I made a solid body that is shape I want the car to be. I then used the shell feature with the thickness of my carbon layers + the honeycomb. This is an easy way to represent the monocoque for modeling, but it doesn't work so well for FEA.
How do you do FEA analysis on a monocoque? I couldn't imagine its efficient to model the inside layers, outside layers, and core separately and then do the analsis on an assembly. I am using mechanica. Maybe Ansys has some tools that make this pretty easy, but I'm pretty sure mechanica does not.
In general I was wondering if somebody could give an overview of how they do composites analysis? This would be a big help.
