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
Objective:
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.
STEPS:
Things We learned During this challenge
- Geamoetry checkup
- Topology cleanup
- Creating faces
- Filling holes
- Assigning PIDs
- Surface meshing complex geometry
1) We can obesrve in the geometry there are more errors patches holes to identify the more minute errors check-geometry and see the errors.
After fixinf the errors the Geometry checks is
2) Creating curves to use it as reference for creating new Surface.
3) Using Fill Hole option to fill the holes on the geometry
4) Creating New Surface to close the geometry.
5) Assigning PID's
Here we assign a different PID to different part of geometry for our convenience dor meshing and fixing any error in particular Part.
Turning On/Off PID will show results as follows
6) Surface Meshing
Result
- Case 1 , Mesh length = 1 mm
- Case 2 , Mesh length = 3 mm
- Case 3 , Mesh length = 5 mm
CONCLUSION:
By concluding all the above three cases (1mm,3mm,5mm)
1mm mesh gave a fine geometry without changing the sketch of the geometry in case3 i;e 5mm the head of the pressure valve has uneven surface . By the finer mesh the results will also will be accurate in the simulation. From the above 3 cases it is concluded that the case1 with 1 mm target length has little to no defeaturing and has retained the geometry of all components even though case 2 is giving the best results.
But the catch is that case1 increases the computational time. To achieve this the components need to be meshed individually with different target lengths.
