Week 5 Challenge : Surface wrap on Automotive Assembly
Aim/Objective
Perform Surface mesh on automative assembly of engine+transmission+gear box with help of surface wrap.
Procedure
We will follow following steps:-
Step1) Check geometry of engine and solve the topo errors
1.1) Search for all rings found at the outer surfaces of engine, and delete them 1-by-1 all.
1.2) They are generally found in the fillet area of an edge.
1.3) Use the help of hiding the wanted surfaces and deleting all unwanted ring surfaces.
1.4) Fill all the holes present on the outer surface of engine leading inside engine using FaceFitted.
1.5) Check the whole engine if it is a closed shape or not without any errors
1.6) Perform the process once again if showing error.
1.7) Deleting the common faces is optional, as it does not matters while Wraping the component.
Step 2) Repeat the process for the gear box
Step 3) Repeat the process for the transmission
Step 4) Assembly of all 3 automotive compnents.
4.1) Bring parts 1-by-1 by File<Merge
4.2) Follow the below parameters for merge parameter
4.3) Fill holes if exists any more by new face feature.
4.4) The assembly is reade for surface mesh if showing no errors.
Step 5) Perform Surface Wrap
5.1) Choose a best view
5.2) Choose Elements<Wrap
5.3) Compress the not required PIDs
5.4) Double-click on empty to give the name 'Full_Wrap'
5.5) Double-click on Untitled to give the TARGET LENGTH of 3mm.
5.6) Select all the PIDs and checck their status.
5.7) If the status is clear, Run the Wrap operation
5.8) It's completion is going to take 10-15mins.
Step 6) Check the sheet made by hiding some entities
Learning Outcomes
We learnt how to simplify the Surface meshing required at time CFD application like the wind tunnel simulation, with help of Surface Wrap feature.
Result
The assembly is sheet meshed properly. Which can be checked from FE-Mode option available below.
Conclusion
The sheet produced for the CFD applications.
