Assignment 1-2D Meshing Challenge

Objective:

To Clean geometry, create Mid surface and create 2D mesh with given requirement for the given three geometric files. Then to assign proper thickness by creating generic property.

Mid surface creation & Geometry Clean up:

First the 3d Geometry must be cleaned for any imperfection to make a single closed surface.

The operation like following are used.

Geometry--> Create--> Surface-->Spline/Filler

Geometry--> Edit--> Surface-->Trim with line

Geometry--> Delete--> Surface

Then Mid surface of the part is created using following command.

Geometry--> Create--> MidSurface-->Auto

Geometry -->Defeature-->surface fillets-->select surface-->remove

The resulting surface is cleaned and simplified with following commands

Geometry--> Create--> Surface-->Spline/Filler

Geometry--> Edit--> Surface Edge -->Toggle

Geometry--> Edit--> Surface -->Untrim

Creating Mesh:

The simplified surface is meshed using command such as automesh, ruled mesh, rebuld mesh, mesh edit, edit element, split element.

Assigning Material and thickness.

we will assign thickness of each mesh structure same as of the main component.

Conclusion

Thus the given Geometry is simplified and meshed.
