Note: Remember the tsai-wu stuff from above? apparently you can code ANSYS to do it:

Geometry Preparation of FSAE Composite & Monocoque Chassis in ANSYS SpaceClaim - Part 1

Basically just a demonstration of how to generate a good mesh.

Some notable tools:

• Stich - select this tool under repair to make your mesh better

• Split edges - merges all edges that ansys thinks are seperate

• Imprint - if you have suspension mounts you can do this so coincident edges are “imprinted” (red areas)

• Can also create “origins” at tire locations (unhide tire) if applicable in order to simulate torsion

Materials & Meshing Setup for FSAE Composite & Monocoque Chassis Using ANSYS Mechanical - Part 2

In ANSYS mechanical do the following…

1. Upload your model

2. Go to engineering data and remove the default materal, then go to engineering data sources → composite materials

   1. Should you want to use a material other than those already in ansys, go to DoD Composite Materials Handbook (has mat properties)

3. Adds epoxy carbon woven, honeycomb, and resin epoxy (last two are relevant to what we want)

4. Close engr data tab and go to model tab

   1. If there is a question mark then smt needs to be fixed before you proceed

5. In materials tab u see ur materials

6. Mesh it

Image Added

Note that curves and suspension attachment areas are weirdly meshed (see part 1 image)

Supposedly if you change element size to 10mm, Capture Curvature to “No”, and select faces of high curvature then “insert → face meshing” your mesh would be a lot better.

7. From there you can go to “Named Selections” select various panel(s) and name them things like “Top Mold” “Bottom Mold” etc.

   1. Helps with defining materials.
