Week 3 Challenge : CFD meshing on Turbocharger

Aim:

To perform the 2D mesh for the given turbocharger model

Procedure:

Do the geometry clean up by identifying and  deleting the overlapping surface. thorough examination has to be done to find the overlapping surfaces.

Identify the single cons and triple cons and delete all

If necessary keep the triple cons

Ensure the continuity of all the regions. clear the discontinuities.  If any discontinuities are present it wil show intersection error during volumetric meshing

Assign the name for all PIDs

Do the 2d meshing for the individual pids with the given size.  set the length and macros with the given size and set the mesh length and quality

if 2d meshing is not done in some region redo that

check the no of elements and element size

click define option for auto detecting volume 

delete the unwanted volume like thickness element from the parent geometry

Do the  3d mesh by selecting cfd tetra mesh option

check the no of elements and element size 

Learning outcomes:

Geometry cleanup

3d meshing and deletion of unwanted volume 

checking for discontinuities

Result 

volumetric meshing of given turbocharger was done

conclusion

this video is very helpful about volumetric meshing in ANSA
