OpenFoam (v9) - Aerospike CFD
How to Run It?
IMPORTANT: By default the UNV file has already been imported to OpenFOAM, thus you can skip to step 3)
0) ./Allclean
1) UNV file to OpenFoam
ideasUnvToFoam meshes/aerospike_refined_2.unv
2) Go to polyMesh/boundaries and change the types!
- walls -> type: wall
- front -> type: empty
- back -> type: empty
- symmetry -> type: symmetry
3) Field initialization to help the solver
setFields
4) Decompose in 4 parts (can do more or less depending on your setup)
DecomposePar
5) Run the solver in PARALLEL ("> log" saves the output to a file named log)
mpirun -np 4 rhoCentralFoam -parallel > log
6) ReconstructPar
7) paraFoam
OTPIONAL: You can check the residuals (in post-processing or on real-time) using the bash files
./plot_k_omega.sh
./plot_U.sh
