How To Build a Project - Exhaust manifold
The following screencasts will guide you through a CFD simulation project with an exhaust manifold.
4.1 Start a Project
- Generate the project folder
- Get your geometry file
- Load it to Salomefor preparation
4.2 Prepare the Geometry
- Geometry preparation
- Close the geometry
- Further preparation for repairing
4.3 Repairing the Geometry
- Further reparing the geometry for the next steps
4.4 Surface Triangulation
- Generate patches for OpenFOAM
- Showing the differences between CAD exported STLs and manuel triangulated one
- Triangulation of the patches
- Generating the background mesh
4.5 STL Preparation
- Exporting the background mesh and STLs
- Preparing STLs for a region STL (compound)
- Checking for water proofness
- Transforming the background mesh to an OpenFOAMmesh
4.6 First snappyHexMesh
- Meshing the geometry with snappyHexMesh
- Setting up the snappyHexMesh file
- Explaining a few things about the snappyHexMeshDict and the keywords
4.7 Optimizing the Mesh
- Further discussion of different keywords
- Optimizing the mesh
- Feature snapping
- Implicit and explicit feature edge snapping
- Generate feature edges
- Generation of layers
4.8 Boundary Set-up and First Run
- Set-up of simple boundary conditions for p and U
- Start the solver
- Check out the first numerical results
4.9 Advanced Boundary Conditions
- Set-up of more physical boundary conditions
- Discussion about the boundary face calculation
- Building a mixed boundary condition (codedMixed)
