Week 4 - 2D Meshing for Sheet Metal

Procedure:

• Open the cad model in ansa pre proccesser.
• Check the geometry from the tools section mentioned as 'check'.
• Resolve the geometry issues.
• Generate the mid surface of the given cad model 'Manually' or 'Automatically'.
• Manually: Using the 'offset' option in the faces module.
• Automatic: Using the 'mid surfacing' option in the faces module.
• After generating the mid surface assign a separate property using the 'set PID' option from the faces module.
• Then switch to the mesh module And Assign the length i.e. 5 to the mid surface using the length option in the parameters module.
• After that check whether the holes are correctly aligned with the nearest parameters or not
• If not then Allign them using the slide option parameters module
• Then check the numbers on it should be an even number
• Then start meshing the features first and face using the best option from the mesh generation module.
• To get a better mesh, Make sections to the faces using cut or pro.cut in the Macros module.
• Using the Reconst option we can reconstruct the mesh.
• Using the smooth option we can smooth the mesh.
• Using the split or swap option we can rectify the errors in the mesh.

Result: hence, the mesh is generated to the given Cad model with the Required Quality criteria
