Assignment 1-2D Meshing Challenge

AIM:- 2D MESHING OF COMPONENTS USING HYPERMESH.

• Practice
• Clip Repair
• Mounting Bracket

OBJECTIVE:-

• 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.

MODEL-1:- PRACTICE

STEP-1

• Import the model in Hypermesh.

STEP-2

• See the model in topo mode to check red/yellow linw which describe are abnormalities present in model.
• These abnormalities are eliminated by providing proper topology or toggle under quick edit in geometry toolbar.
• More than single surfaces present in the model can be deleted using component delet entity, it appeares as a yellow line in the model.

STEP-3

• The geometry cleanup tool itself allows to perform various task ranging from adding, remolding points along with spliting geometry, toggeling edges, editing nodes and distance.
• Once geometry cleanup the model is ready for extracting midsurface. Mid surface extracting using automatic midsurface tool.

• We obtain midsurface.

STEP-4

• Set the quality parameters in the criteria file min size 3.5mm and max size 7mm and target element size is 5mm.

STEP-5

• After generating midsurface the model is ready for 2D meshing, the model meshed with targeted mesh size 5mm.
• Meshed entire model.

STEP-6

• Create new property and assign thickness.

MODEL-2:- CLIP REPAIR

STEP-1

• Import the model in Hypermesh.

STEP-2

• Check errors present in the model. No errors found in the model and hence no need clean the model.

STEP-3

• Generating midsurface and then mesh.

MODEL-3: MOUNTING BRACKET

STEP-1:-Import the model.

STEP-2:- Generating midsurface.

STEP-3:- Meshed the model.

RESULT:- I learn in this chellenge how to use geometry clean up tools and also learn how to generating midsurface and assign the thickness.
