Week 5

AIM: To mesh the given solid component using tetra elements

PROCEDURE:

 Step 1:-

• First step is to find how many volumes are given
• In this given model there 4 seperate solids

• We should define 4 seperate volumes
• Right click on one property isolate it by show only option, work on each solid seperately

Step 2:-

• First cleanup the geometry by TOPO
• Check for geometry errors 

note: Make sure there are no single cons for solid meshing

• fix the geometry errors

Step 3:-

• Next step is to perform surface mesh.
• Before meshing assign the mentioned quality criteria values, such as minimum, maximum and target length.
• Perform spot mesh by keeping element type as ortho tria for curved regions like fillets,

• Spot mesh the flat regions by keeping the element type as tria

• After performing the surface mesh, make sure there is no OFF elements

Step 4:-

• Next step is to perform solid mesh
• Assign tet collapse quality criteria in solids tab.

• Volume will not be defined initally, define the volume 

• Now the status should be defined by either tetra fem or tetra rapid method
• Make sure tet collapse error is zero
• Use fix quality option for auto fix the collapse error
• If collapse error is occuring on surface do not use fix quality it might form Raise and kinks.
• Instead use Mv Free option and fix the error.

Step 5:-

• Repeat the same steps for each and every solids 
• Cross section views of all the solids are shown below

• Final result

• Final cross section view

LEARNING OUTCOMES:

• Understood how to define the volumes for different solids
• Understood topics of unstructured ans structured mesh 

COCLUSION:

• Surface and solid mesh is done for the given component without any OFF elements.
