Week 3-Meshing of Hood Challenge
REPORT
OBJECTIVE
To mesh the given component without failing the quality criteria.
PROCEDURE
The first step is to generate midsurface, i generated midsurface using the command 'geom-midsurface.
There was some issues with the generated midsurface, is shown below.
I fixed it using 2D-spline and quick edit-toggle edge.
The model is symmetric so i deleted the one half of the model.
Then i started geometric cleanup so the geometry will be ready for meshing.
Quick edit is used for this operation, given washer split for holes and created cuts on the geometry.
I gave the quality criteria values to the 2D- qualityindex and started meshing surface wise. We cn adjust the number of nodes while meshing, by that we can improve mesh quality. Further improvement is done by remeshing and using qualityindex-cleanuptools.
2D- edit element, replace point is also used to improve meshflow.
this opposite trias are fixed using qualityindex-drag tria element, replacepoint, and then smooth- size correction.
The mesh below is corrected by remeshing and adjusting the number of nodes.
For the feature area, elements are splited using split quad elements so that the elements will not fail.
Fixed all the quality riteria using these commands. There is no elements failing for the quality criteria. Now its time to reflect the model ( tool-reflect).
After reflecting, i checked for tool- edges, in there removed gap between the old and new surfaces. And checked for edges.
There was a problem as shown here, connectivity problem between the elements that reflected.
This problem was fixed using 2D-replace and 2D-edit element-create.
Finally the model is ready qualifying all the quality criteria. Assigned thickness for the mesh.
RESULT
The meshing is succesfully completed for the given component.
There is no element failing for the quality criteria. Inorder to satisfy quality criteria there is a slight compramise in the meshflow considering the component have a lot of features. I was able to attain a decient mesh flow for the component and there is no connectivity issue. Please check the file below.
