Week 3 - 2D meshing for Sheet metal

Objective : To generate a mesh with given quality criteria on the given CAD geometry

CAD Model : Car Hood

Procedure:

• Import the CAD model stp/iges file.
• Geometry cleanup - Using the check manager, checking for geometry errors and cleaning them up using TOPO module.
• Measuring the thickness of the model after geometric cleanup.
• Mid-surface generation : Can be done in Manual and Automated ways. Created the mesh using Skin option under mid-surface tab in TOP module's Face button.
• Checking the geometry again on the generated mid surface using checks manager, but with single cons criteria switched off.
• Setting up the mesh parameters and quality criteria (F11) according to the given standards. Generating the Mesh using Mesh Generation under MESH module.
• Checking for the mesh quality and flow, cleaning them up using Shell Mesh, Macros, Elements buttons in MESH module.

Results : Mesh generated passing the given quality criteria and optimum mesh flow conditions.
