Week 3 Challenge : CFD meshing on Turbocharger

Aim/Objective: Perform Volumetric mesh for the required volumes as per target length given for each component

Procedure:

1. Import the model to ANSA.
2. Delete the overlap surfaces
3. switch to the TOPO module.
4. Create the surface which is deleted while deleting overlap surface.
5. Run the geometry check. solve the single cons.
6. solve the triple cons if its required. use the release option in cons to convert triple cons to double cons and use the top in faces convert to single cons to double cons.
7. Close the volumes.
8. Create PID with respect to different component. Check the model thoroughly for overlapped surfaces and single and triple cons.
9. Switch to Surface mesh .
10. Define target length and type in mesh parameter and quality criteria with respect to the components.
11. Define the length perimeters and macros
12. Mesh the model one PID by one PID by spot mesh.
13. check the unmeshed the surfaces. if the target length is diferent against neighbour surface, surface wont be formed. we need to give the target length in the range to the those surfaces.
14. After the surface mesh, move to volumetric mesh module.
15. define the volumes and detect on whole data base. then ok.
16. we will get list of the volumes detected by. Delete the unnessarry volumes.
17. select the required volumes. Click the remesh. Select the type Tetra CFD. Mesh the selected volumes.
18. Volumetric Mesh will be completed. Check the model thoroughly.

Learning Outcomes:

1. Check and Clean the model using Topo module clearly
2. usage of relase and topo command
3. mesh the surface to critical surface
4. Usage of cut in macros in mesh module
5. define the volume and mesh the volumetric model

Result & Conclusion:

Mesh the model with respect to Target length to the each components sucessfuly and attached the model to this report
