Hex-dominant automated: Mesh around a spoiler¶
The content of this tutorial is not up to date with the current live version of SimScale. The tutorial setup and the results are still valid! Please do not get confused if styles like buttons and entity names have changed in the meantime.
This short tutorial shows how to create a mesh using the automatic Hex-dominant for wind-tunnel/external flow for the analysis of flow around a spoiler.
Link to tutorial project containing the geometry:
- Geometry can be uploaded by drag and drop or can also be directly imported from Onshape.
- For this tutorial, you have to import the tutorial project into your ‘Dashboard’ via the link above.
- Once imported, the ‘Work bench’ is open and you will be in the ‘Mesh creator’ tab.
- Click on the CAD model to load the model in the viewer.
2) Mesh generation¶
Click the available geometry. Then click on “Mesh Geometry” button in the options panel.
Select the mesh parameters according to the problem. Fineness increases the mesh quality at the cost of increased mesh size and computational time. Use layers addition to add layers at the geeometry boundary for better mesh resolution near the boundary.
For external flow cases the flow domain (baseMeshBox) should be 2-3xL upstream, 4-6xL downstream and 2-3xL in the cross-wind directions from the object. Here ‘L’ is the body length in the flow direction.
