PROCEDURE
The procedure required to accomplish this task is done in four major step.
Import And Geometry Check Of Component
Generation Of Midsurface and Geometry Clean-up
BODY 3
BODY 2
BODY 1
Meshing Of The Component
Before starting meshing, i identified certain areas which can make the meshing task dificult and i created split surface lines to section these surfaces to make my meshing easier.
BODY THREE MESH
Half mesh
Full reflected midsurface
Full Body Three mesh on midsurface
BODY TWO MESH
Half mesh
Full reflected midsurface
Full Body Two mesh on midsurface
BODY ONE MESH
Half mesh
Full reflected midsurface
Full Body One mesh on midsurface
Making Necessory Checks On Final Mesh
Images of checking normals
RESULTS AND CONCLUSION
Below is an image of the final mesh of all three components after generation and their quality mesh criteria failure percentages.
CONCLUSION
The components where mesh successfully and passing all quality criteria set in the tool test. Below is an image of the final meshed component.
