Week 4 - 2D Meshing for Sheet Metal
AIM : To check the geometry cleanup on given 2d cad model and generate midsurface then meshing mid surface according to the given quality criteria.
CAD MODEL :
PROCEDURE :
1. GEOMETRY CLEANUP
2. GENERATING MID SURFACE
3. ENTERING GIVEN ELEMENT QUALITY CRITERIA
4. MESH GENERATION
5. RESULT
GEOMETRY CLEANUP :
- IN THIS GEOMETRY CLEAN UP PROCESS THE GIVEN CAD MODEL WAS THROUGHLY CHECKED FOR GEOMETRICAL ERRORS SUCH AS DEMORED FACES AND TRIPLE CONS
- THEN THE SHAPE OF PLASTIC MODEL WAS REFINED BY USING SMOOTH TOOL.
- FINALLY WHILE RUNNING GEOMETRY CHECK IN CHECKS TAB IT SHOWS THAT NO ERROR WAS FOUND SO THE GEOMETRY CLEANUP IS SUCCESFULL.
GENERATING MID SURFACE :
- THE MID SURFACE WAS TAKEN ONLY AFTER THE GEOMETRY CLEAN UP WHEN THE CAD MODEL PASSED THE GEOMETRY CHECK COMPLETELY.
- AND MID SURFACE WAS CARRIED OUT USING MANUAL OFFSET.
- FINALLY MID SURFACE GENERATION IS SUCCESFUL.
ENTERING QUALITY CRITERIA :
- AFTER GENERATING MID SURFACE THE GIVEN QUALITY CRITERIA WILL BE ENTERED.
- MESH GENERATION SHOULD BE BASED ON THE GIVEN QUALITY PARAMETERS AND IT MUST SATISFIES THE GIVEN PARAMETERS.
MESH GENERATING :
RESULT : SINCE THE FINAL MESH OF CCB ASSEMBLY CAD MODEL SATISFIES ALL THE GIVEN ELEMENT QUALITY CRITERIA HENCE THE MESH GENERATION IS SUCESSFUL.
