Week 8-Challenge

OBJECTIVE

3D Meshing:

Elements sizes: Min- 2mm, Target- 5mm,Max- 7mm

Tet collapse: 0.15

1. Create Teramesh for Housing

2. For the given Model,

Model-2, Model-4,

Create 3D mesh with 6mm

PROCEDURE

1 create tetramesh for housing

• CAD File was imported using import geometry.
• Geometry cleanup were done like toggle lines, delete surface, filler surface.
• Once the cleanup was done 2d mesh on the surface was created.
• 2D mesh was created using automesh.
• Required measurements were taken into account while deciding the specification of the element size and orientation.
• Quality check was done once the mesh was done, using element check, smooth, element optimization. Replace node.
• Once 2D mesh was optimized 3d mesh was created using tetra mesh in 3D panel
• All the 2D elements were selected and 3D mesh was created using them.
• Once the 3D element was created quality check was performed using tetra collapse.
• All the falling elements were masked and then rectified.
• Height of the falling elements was improved using node distance and replace node.

Result

Quality check:

2. Create tetra mesh for the two given model

Chassis assembly

• Model was opened in hyper mesh
• Model contain all solid component so volume teramesh approach was taken.
• 3D mesh were created with give specification.
• All the component were meshed separately because of the student edition limitations.
• Once the 3D element was created quality check was performed using tetra collapse.
• All the falling elements were masked and then rectified.
• Height of the falling elements was improved using node distance and replace node.
