Assignment 1-2D Meshing Challenge

Assignment 1

Aim

To create and mesh the mid surface of the given models

Procedure

So in parameter file settings if we change the range to 2.5 mm on remeshing hypermesh automatically fills such gaps

Figure 1

Figure 2

In the first model,there are several free edges and manifold edges that need to be solved

Figure 3

The free edges can simply be toggles and the manifold edge is simply an extra surface that can be deleted
In the case of figure 4, it is simpler to simply delete the surface and create a new one

Figure 4

Figure 5

Figure 6

Figure7

The mid surface can be creating by using the automatic mid surface option after which you can start meshing
Toggle any unnecessary lines/areas that fail the min length criteria.

Figure 8

Set the criteria accordingly in the criteria file settings in preferences.
Mesh the model surface by surface and verify connectivity using edges in tools option.
After verifying connecting solve any off elements/unnecessary trias using rebuild mesh/smooth/2d quality critieria tools/split/etc
You can observe hypermesh ignoring holes less than 5mm dia after remeshing.

Figure 12

Model 2 has several unnecessary nodes that can be deleted with temp node option.

Figure 17

Using auto midsurface option to generate the mid surface.
The feature needs to have its construction lines rearranged to avoid min length failures as shown.
It is possible to simply mesh one portion and copy it to the other surfaces using the position/reflect/rotate tools available
