Week 3 Challenge : CFD meshing on Turbocharger

1) Import the CAD model to workspace

2) Geometry checks

3) Fix the errors

4) After reparing

5 ) For meshing

A) For turbo casing , compressor and inlet casing cover

1. Select the mesh module >> perimeters >> length >>5 mm in perimeters and in macros
2. Max target lenght = 7 mm Min Target length = 3mm Mesh type = tria( Meshing parameter)
3. Max target lenght = 7 mm Min Target length = 3mm(Quality criteria)
4. Upper deviation = +2mm lower deviation = -2 mm

B) For blade stage 1 &2 and shaft rotor

1. Select the mesh module >> perimeters >> length >>1 mm in perimeters and in macros
2. Max target lenght = 1.5 mm Min Target length = 0.5mm Mesh type = tria( Meshing parameter)
3. Max target lenght = 1.5 mm Min Target length = 0.5mm(Quality criteria)
4. Upper deviation = +2mm lower deviation = -2 mm

C) For impeller

1. Select the mesh module >> perimeters >> length >>2 mm in perimeters and in macros
2. Max target lenght = 3 mm Min Target length = 1mm Mesh type = tria( Meshing parameter)
3. Max target lenght = 3 mm Min Target length = 1mm(Quality criteria)
4. Upper deviation = +1mm lower deviation = -1 mm
