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
Meshing :
Quality Check :
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 :
