Week 4 - 2D Meshing for Sheet Metal

Report on Generating mid surface and 2D mesh elements after geometry clean-up of CCB water support system assembly as per given quality criteria by using ANSA software.

Objective:

The main aim is to mesh the mid-surface of CCB water support system assembly with given quality criteria of mesh parameter using ANSA Software. And to use efficient method to do geometry clean up and get mid surface of inner panel.

Procedure with CAD model images:

• The given CAD model from Design team.

As shown in figures below the given cad geometry need to do geometry and topology clean up.

Fig. 1: CAD model of CCB water support system assembly.

Fig. 2: geometrical distortion.

• After importing .IGES file in ANSA, observation found that 3 unchecked areas present where geometry needs to be check for clean-up.
• Start with checking single, double and triple cons. I have used Topo option in faces group to remove unnecessary single cons and Release option in CONS module.
• To refine feature areas of geometry, used fine option available in Auxiliary group.
• The mid-surface extracted using automatic method to reduce time. The mid-surface option available in faces group used for extracting mid-surface.
• The separate properties were assigned for extracted mid-surface using set PID option available in faces group.
• The whole clean up and refinement was done for the mid-surface.
• Before going for meshing check geometry has been executed.
• Cut and project cut option used which are available in macros group to compromise fillet and feature areas to achieve mesh parameter and quality criteria.
• In meshing the given mesh parameter and quality criteria has set for meshing.

Fig. 3. Given quality criteria.

Fig.4 Given mesh parameter.

• The meshing started by using mesh module, Best mesh option were used in mesh generation group for meshing.
• The reconstruct mesh option used which is available shell mesh group.
• Split and smooth options also used for better mesh flow.
