Week 3 Challenge : CFD meshing on Turbocharger

AIM: To perform the Volumetric Meshing of Turbocharger

Procedure:

• Firstly we check for geometry error such as double con, edges etc (if found then clear it out by using faces, fill holes etc options)
• Then we use the tab of HOT POINT, to use the Parametric option
• Then we use the Multi Project.
• Then we use the tab of FACES on it we use the feature of cut to create the symmetricity
• Then create a required PID such as below:
  
  
  
  
• After it, we switch the tab to MESH, in it we use the tab of PERIMETER, in it we use the LENGTH tab (perimeter & macros) for deciding the mesh length.
• Then we adjust the mesh parameter and quality criteria as given in question

• Then we check the geometry  

  Then finally we use the SPOT MESH, to generate the MESH as follows (the 2nd image is of wireframe type): -

• 
• 
  
  
• Then we perform the volumetric meshing as follow:
  

• Learning Outcomes:

  • Got to know about how to proceed and generate the Mesh in a directional way.
  • Got to know about the concept of nodes and different forms of meshes.
  • Got to know the concept of various tools such as parametrical option, the concept of projection, and cut feature too.

  Result & Conclusion:

  • For Shell Total Triads: 905488.
  • Fully generated TRIA mesh and as per required target length.
  • For Volume Total Tetras : 477910
