Vertical-Axis Wind Turbine mesh

This makes a mesh of a vertical-axis wind turbine.

Requirements

This has been tested with gmsh 3.0.6. You will also need OpenFOAM.

It will be helpful to have ParaView.

How to run

1. Generate the mesh.

gmsh ./1.txt -3 -smooth 2 -clmax .25 -o ./Turbine.msh

2. Converts mesh file to OpenFOAM.

gmshToFoam ./Turbine.msh
createPatch -overwrite
renumberMesh -overwrite

NOTE: Kunal had an issue so he added $End at the end of the Turbine.msh and it ran ok.

3. Sometimes the 0/ files have been overwritten, so copy the original files from 0.orig/.

rm -rf 0
cp -rf 0.orig 0

4. Decomposes the mesh into pieces, so you can run in parallel.

decomposePar

5. Remove the mesh file; you dont need it anymore.

rm -rf ./Turbine.msh

6. scp files to the supercomputer (i.e. Comet).

7. Remove all intermediate files:

rm -rf processor*
rm -rf *.pos
rm -rf *.msh
rm -rf constant/polyMesh

8. Run OpenFOAM on the supercomputer!

Help

If you want to run it locally, you can edit decomposeParDict to 4 (or however many cores you have), go through the process, and run

mpirun -np 4 pimpleFoam -parallel | tee pimplefoam.log
