Project 1 - Meshing of Floor Panel
Aim :
To take a proper midsurface for floor panel
Geometry check and cleanup needs to be done for proper mesh flow
Feature lines should be proper to maintain he shape of geometry
Proper mesh flow and quality criteria needs to be obtained
Component : Floor panel
Quality Criteria
Target Element Length = 5 Units
| 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
Steps 1
Import the Geometry check for single cons if present use topo as required
Perimeter length and macros given for better resolution
check for geometry if there are errors needs to be fixed by auto fix or manually
Faces new option is used to create new surface wherever required
Pid thickness is assigned for the geometry
Steps 2
When geometry is fixed midsurface is taken by Manual offset method
Check for proper midsurface thickness is assigned on offset the midsurface is extracted
According to the minimum length unwanted feature lines are supressed Using Macros join command
Construction lines are added using macros cut to get proper mesh flow
And hot points deleted if not required using hotpoints delete
Steps 3
Quality parameters are added Then meshing the geometry is performed
Meshing is done throughout the geometry with all the feature lines captured
Best mesh option is used to perform the meshing from mesh generation
Trias are avoided and kept minimum by using reconstruct for improving the mesh flow
The off elements are cleared to get proper mesh flow with feature lines
Steps 4
The changes are slightly done to avoid off elements by adjusting the feature lines
Minimum length is maintained throughout geometry for proper mesh flow
Split and swap options are used to improve the mesh and avoid trias
Shell mesh collapse and grids move options are used to avoid trias
Then used shell as solid option checked and submitted
Learning outcomes :
Cleaned geometry properly for proper mesh flow
Pid is assigned for the geometry
Mid surface taken properly for meshing
Meshed with proper flow and capturing feature lines
Quality parameter is obtained with proper mesh flow
Conclusion :
Floor panel midsurface is extracted and mesh obtained as per quality parameters The complete file is attached for reference
