Week 2 Challenge : Surface meshing on a Pressure valve
Aim
For the given model, check for the geometrical errors and perform Topology cleanup accordingly. Set three different target lengths as three different cases and mesh the model.
- Target length = 1mm, 3 mm and 5 mm (i.e. 3 cases)
- Element type = Tria
Apply any one target length from the above at a time for the entire model as One case. Submit 3 different models for 3 cases.
Write a detailed report on your meshing process and also mention which case is giving good results along with the reason.
Procedure
- First we need to cleanup the geometry from errors
- The errors are found through a checkup
- For CFD applications the solid should be sealed if the flow is internal as in our case
- So the holes are closed with fill hole option for Inlet and Outlet and creating new faces
- As a next step I have removed the lines which are much closer than the mesh length to avoid difficulty in fitting the elements
- Then PID is are assigned carefully and they are termed as Spring, Coloumn, Base, Valve head, BOdy , Inlet , Outlet and body
- Each PIDs are meshed seperately for each cases
- Target lengths are also assigned accordingly
Learning outcomes
- Geamoetry checkup
- Topology cleanup
- Creating faces
- Filling holes
- Assigning PIDs
- Surface meshing complex geometry
Result
- Case 1 , Mesh length = 1 mm
- Case 2 , Mesh length = 3 mm
- Case 3 , Mesh length = 5 mm
Conclusion
- Surface meshing of the given solid is done in three different nodal length as three different cases
