Week 8-Challenge

Aim :

Create 3D mesh of the following components :

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

Tet collapse: 0.15

Component 2 : Model 2

Solution :

Defeaturing :

Since our minimum length is 2 mm we have to remove the areas which fall below 2 mm using the defeature command as shown below :

All errors due to defeature tools have been removed with the help of quick edit as shown :

Using the utility method as shown below :

We get the following mesh :

The following components have failed for tetcollapse :

Using tetra remesh we have removed the following as shown below :

Part 2 :

Using the method we get the mesh for the second part as shown :

Whole Meshed Component :

Component 2 :

Geometric Clean up :

After defeaturing we need to clean up a few areas as shown .

Using the automesh tool we have created a shell elements as shown and after that we have used 3d mesh to create elments as shown below :

Component 3 :

Since component 3 has many subparts we will be meshing it part by part :

Part 1 :

Using defeature tool we have removed the fillets which will fail for the element

2D Shell mesh has been created as shown below :

This shell mesh will be converted into 3D tetra mesh as shown below :

Quality Check :

We will now check for tetcollapse :

As you can see the 0.6 % have failed

Using element cleanup we have reduced the failed elements to zero

Part 2 :

Geometric Cleanup :

Using defeature tool we have removed the areas which will fail for 2 mm length and 8mm length as shown below :

Meshing :

Quality Check :

Part 3 :

Using quick tetra mesh we have meshed with 6 mm element size

Part 4 :

Using quick tetra mesh we have meshed with 6 mm element size:

Mesh Quality :

Reflect :

Using the distance command we have made a point in between as shown below :

Using the reflect tool we have mirrored the elements as shown below :
