Week 2 Challenge : Surface meshing on a Pressure valve
Aim- Elminating geometrical errors from model and and perform topology cleanup. Perform surface mesh for various target lengths.
Objectives -
- Perform model cleanup.
- perform surfac mesh for various length such that 5mm, 3mm and 1mm.
Procedure
- Open Ansa software and load given model
- Check errors
- Executing to check errors
- From model we see there are lot of opening and surface errors
Errors may contain a single cons, some extra or unnecessary hot points, openings, some overlapping surface etc.
Eliminating those errors using different options like planner, fitted, cons, fill holes,and new cut etc.
After eliminating errors our model look like this
- Creating properties to model
After all properties and corrections we can move for meshing
Apply length and macros
Target Length 1mm
- Apply mesh
We get our mesh (1mm target length)
- Target Length 3mm
Target Length is 5mm
Learning Outcomes-
- Maximum Number of elements gives more accuracy
- Low number of nodes means low number of elements and less accuracy
- Use of join tool to perform geometry cleanup.
Results
1. Target length 1mm
2. Target Length 3mm
3. Target length 5mm
Conclusion
- Triple cons are not error
- Selection of length and macros is vey necessary specially when there is low curves or some complex geometry
- higher elements gives more accuracy but needs more time for mesh generation
- Higher elements gives smoother results
- low number of elements gives low accuracy. But fast in operation
