Week- 5 - Solid meshing

AIM; To perform the Tetra meshing(unstructured mesh) for the given Rear view mirror component and mesh the component according to the given Quality criteria.

Steps to be for Tetra Mesh;

1. Importing the model.
2. Perform the topo on the given model.
3. Geometry checks should be done.
4. Fix the Quality Criteria.
5. Remove the unwanted construction lines which are below the min length quality criteria.
6. Capture the mesh with Ortho tria and trias.
7. Finally the tetramesh should pass the Tet collapse quality criteria.

S.No	Quality Criteria	Value
1	Target/Average length	1
2	Minimum Length	0.5
3	Maximum Length	2
4	Tet collapse	0.2

Given model;

Topo

Gepmetry checks;

Fixing the Quality criteria;

Setting the perimeters;

Measuring the dimensions of the model and defeature the lines which are failing the minumum element length;

2D MESHING;

• After performing all the geometry clean up we should perform shell mesh on the model.
• mesh should be done by using both the otho Tria and trias on the model.
• Mostly the ortho trias are used in the fillet and circular regions where to capture perfectly without any deformation of mesh.
• trai elements are used where flat surface regions.
• And all above elements should pass the quality parameters.

Volume Mesh Deck;

Volume Mesh;

• In order to perform the volume mesh we need to define it and we need to add it to list.
• Then we need to go to the list and right click it then selects remesh and we can select tetra fem /tetra rapid
• After meshing we need to check the quality if any tetcollapse are present we need to eliminate them by manually or by using fix quality

Define;

Used to define the volume entites and next we have to create an property Id to the entites.

list

• It is used to enable the handling of defined volumes in the Database.
• And also by using the remesh option we enable to perform the Tetra hedral mesh generation of the volume entites.

Here we need to check the volume mesh which is created inside the model.

CONCLUSION;

• Peform the unstucture mesh(tetramesh) on the given model.
• Shell Meshing using the ortho tria & tria Mesh with respect to the quality.
• Generating the volume mesh by using volume deck.
• Fix the Tet collapse and by this allow the model to generate the mesh according to the mentioned criteria.
