Week 6-Meshing of Hood Challenge
Aim-Midsurfacing the model and meshing.
Objective- For below quality criteria mesh the model,
| S.N | Quality Criteria | Value |
| 1 | Aspect Ratio | 5 |
| 2 | Skewness | 45 |
| 3 | Warping | 15 |
| 4 | Taper | 0.5 |
| 5 | Min. Length | 2 Units |
| 6 | Max. Length | 8 Units |
| 7 | Min angle Quad | 45 |
| 8 | Max angle Quad | 135 |
| 9 | Min angle Tria | 20 |
| 10 | Max angle Tria | 120 |
| 10 | Tria % | 10 |
Procedure-
1. Import the model - First of all import the model by using option import solver deck which is in left corner.
2.Deleting solids-By using the delete option select solid and displayed option and delete.
3.Take mid surface-Go to geometry>midsurface> go for skin option in extraction for uniform thickness >and select the surface >extract.
4.Adding the washer-We are adding the washer near holes because we dont want the tria near the holes because stress concenration near the holes is more.Go to geaometry>quick edit>washer split>set offset value>select the holes.
5.Cutting the symmetrical parts-By deleting the surface we are going to cut the half section of symmtrical part.
6.Toggling-Toggling the lines which are going to fail for minimum length.Go to geametry>quick edit>toggle>select the line and left click.
toggling the fillet lines-
7.Adding the quality criteria-
8.Mesh -Meshing the model by using the automesh in 2d option.
7.Tria removing - For this by using the rebiuld mesh option in 2d we can set the tria element.
Before tria removing the mesh flow is-
By using the rebuild mesh option we set the tria element -
8.Reflect- For symmtrical parts we are using the reflect option in tool module.Go to tool>select reflect>select the middle surface in left window and make as current>Select element >duplicate>current component>select displayed elements>select the node points>reflect.After that delete the in mid of the component.
9.Correct the fail elements by using the quality index tools,element clean up option and rebuild mesh.
completed model without any fail to quality criteria-
Outcomes-Learned about how to midsurface,meshing ,correcting meshing elements and reflect option.
