Cad Model Image :
Initial
Method: Casting
Procedure:
1. Open file in ANSA and Topo the whole Model.
2.Check for Geometry and try fixing by selecting all error, select fix and if the error are still there solve using manual method.
3.Use "Fill Hole' option to fill the Half side
4.Once again check for geometry
5.Go to Mid Surface - Casting and input Target length, Minimum Length and Tick sharp fillet with radius
6. Turn off the 'Faces' and check the meshing
7. To fix the FE use 'Align Manager', Element 'Delete', Element 'Fill', some create curves and us 'Fill', use 'Join', 'Cut' option to create features, faces.
8.After fixing Mid-Surface Input 'Quality Criteria' as given and Apply it.
9.After that go to Click on 'Hidden' option to see quality criteria on surface, if the surface are failing the colour of in which quality criteria its failing, if it failing we have to sometime use 'Join','Cut' cons ,'Delete' the face and recreate new face, sometimes create new Cons using 'Cut' for better mesh flow and 'Reconstruct' or 'Smooth' option. , If the surface is failing 'off' will be shown, if the surface is not Failing on Quality Criteria, then the Surafce is ready as shown Below. We have to also reduce the Trios to Minimum for better result. For reducing tria and creating better mesh flow sometimes use 'Split', 'Swap', 'Smooth','Improve' as per the conditions.
10.Go to quality criteria, click on 'Draw Shell as Solid' and click on apply.
11.After that the meshing of the model is Done using Manual Method. Check the whole Mid-Surface only visibling them to do final check.
Learning Outcome:
During Meshing the model I learn mostly of how to use Casting and Align Manager
Conclusion :
For the Given Component the Casting Method is mostly suitable for Meshing.
