A mesh is critical for any numerical calculation. You may get a never converged calculation, a false result, or a misleading conclusion.

3D scanning software can be helpful for hole auto-detection, but we need to double-check check the result.

Figure 1 is a 3D mesh I’ve scanned. The main issues are:

  • extra layers of mesh as shown in (a) and (c)
  • not smooth (b)

I will solve all those issues using blender in the following blog posts.
