Week 8-3D Tetra Meshing Challenge

OBJECTIVE: To creat tetramesh on 3D componenets with given quality parameters.

MODEL 1 : Housing Model

Quality Criteria for this model:

minimum element size : 2mm

maximum element size : 7mm

target elelment size : 5mm

tet collaps : 0.15

Procedure:

• For this model we have to creat 2D shell elements first then we will convert it into 3D tetra elements by using 3D mesh panel.
• The maximum and minimun element size we need to clear this quality within the 2D mesh.
• After creating 3D elements we will check for tet collaps and need to clear the fail elements.This can be done by remeshing the 3D elements using tetra remesh command.

MODEL 2 :

Quality parameters for this mesh:

target element size : 3mm

tet collaps : 0.15

Procedure:

• In this model 1st we will be using vloume tetra mesh from 3D mesh panel.
• If some error is showing in meshing due to geometrical error in the model the we will go for Quicktetra from utility panel.
• Where we will select the component which we are going to mesh and set the value of quality parameters and then go for mesh.
• After that we need to check for tetcollaps here also.
• 

MODEL 3 :

Quality criteria for this model:

Target elemnt size : 4mm

Tet collaps : 0.15

Procedure:

• In this model we have to follow the same procedure as model 2.
• Either we will go for volume tetra mesh or we can directly go for Quicktetra mesh from utility panel.
• And at last we will go for tetcollaps.
• we will be doing the mesh in one by one component order.
