Part groupings are ways for Ansys software to automatically group pieces together and create automatic connections. We should create two part groups: the truss K-1 and the tertiary subframe surface.
The remaining flexure mounts and rigid mount pad should remain separate entities.
Once the geometries have been assigned to the parts, there are a few thicknesses that need to be applied.
The shell models of the entire subframe part all need a thickness of 2.75 mm, (2.75e-3 m).
