Objectives:
1. geometry cleanup.
2. mid-surface extraction, assign thickness.
3. meshing of the model.
1.Geometry cleanup:
1. Use checks/geometry/auto fix/topo/project cut/cut/release
2. Use delete from hot point section for clear hot points,new from faces.
2.Mid-surface extraction:
1. use faces/offset
2. select the model and assign half of the thickness of the model in pop box which is open by clicking on offset.
3.Assign thickness of every part.
3.Meshing of model:
1. Use hot point/delete
2. check quality criteria and fix it.
3. make better meshflow.
