Assignment 1-2D Meshing Challenge

AIM:

Geometry Cleanup Exercise:

Carry out the geometry cleanup operation on the given 3 files.

• Practice
• Clip Repair
• Mounting Bracket

There should not be any free edges, convert all of them into refine geometry.

• Clean the geometry.
• Extract midsurface.
• Clean midsurface geometry.
• Ignore holes less than dia 5mm.
• Create 2D mesh with target length 5mm, min 3.5mm max 7mm.
• And assign proper thickness, by creating a generic property.

• Then Save in .hm format.

DESCRIPTION:

IN THIS ASSIGNMENT WE HAVE THREE MODELS TO WORK ON AND DO THE MESHING. BEFORE DOING MESHING WE NEED TO CHECK THE GEOMETERY AND FIX THE GEOMETERY ISSUE ONE BY ONE AND AFTER THAT EXTRACT THE MID SURFACE. AND AFTER EXTRACTING THE MID SURFACE CHECK THE THE GEOMETERY FOR THE CLEANUP AND AFTER THE NECCASRY IMPROVEMENT IN THE GEOMETERY THEN GO FOR MESHING AND MESH THE MODEL ONE BY ONE AND CHECK THE ELEMENT QUALITY CRITERIA AND FIX THE ELEMENT ACCORDING TO THE QUALITY.

PROCEDURE:

1. LAUNCH THE HYPERWORKS BY CLICKING HYPERWORKS APPLICATION.

2. OPEN THE MODEL FOR OPENING THE MODEL GO TO FILE AND CLICK OPEN AND LOAD THE MODEL INTO HYPER WORKS AND AFTER LOADING AND CHECK THE GEOMETERY CAREFULLY AND CHECK THE ISSUES WITH THE GEOMETERY.

SA

3. AFTER CHECKING GEOMETERY GO TO GEOMETERY TOOL AND SELECT THE QUICK EDIT TOOL AND DO TH NECCSARY THINGS TO FIX THE GEOMETERY WITH THE TOOLS.

4. AFTER FIXING THE GEOMETERY THEN GO TO GEOMETERY AGAIN AND SELECT THE MID SURFACE AND IN THE EXTRACTION METHOD SELECT THE SKIN OFFSET AND GO BACK TO AUTO MID SURFACE AND CLICK TO CREATE.

5. AFTER MID SURFACE CHECK THE GEOMETERY AND DO THE NECCSARY CHANGES IN THE GEOMETERY. SO THAT THE MESHING QUALITY WILL

BE GOOD.

6. AFTER SETING UP GEOMETERY GO TO 2D MESH TOOL AND GO TO AUTOMESH AND PUT THE ELEMENT SIZE 5MM AND SELECT THE MODEL TO BE MESHED ANDCLICK MESH.

7. AFTER MESHING CHECK THE ELEMENT QUAILTY QRAITERIA AND CHECK WHERE WE CAN IMPROVE THE MESH AND WE CAN DO THE SAME FOR IMPROVING THE MESHING.

8. AFTER CHECKING ELEMENT QUALITY AND REMESH GO TO OTHER MODEL AND DO THE SAME STEPS AS EXPLAINED FOR THE FIRST MODEL.

9. FOR SECOND MODEL WE CAN USE REFLECT COMMAND FROM TOOLS BECAUSE IN SECOND MODEL THEIR IS SYMMETERY SO WE CAN USE REFLECT COMMAND THEIR.

10. GO TO SHIFT F6 TO FIX THE EQUIVLANCE IN MODEL AND AFTER FIXING EQUIVLANCE IN MODEL GO TO SAVE AND SAVE THE MODEL. WE CAN THESE STEPS FOR EVERY MODEL.
