steps to work with CFD

1) Load Mesh File | Compound_Mesh_1.unv in brentscavity2_0.0126L.tar.gz
1.5) Transform to polymesh ideasToUNVFoam
2) transformPoints -scale '(0.00006 0.00006 0.00006)'
compare dimensions of the grid in pixels to grid dimensions in Holly's Paper
3) Use configuration files in 0 and system for pisoFoam
4) Run the Simulation for 1 to 2 days
5) Change the Configuration file for System to SimpleFoam
----------------------------------------------------------
Run SimpleFoam
Plot over line in pisoFoam
----------------------------------------------------------

For step 3 see the video:

Mistakes::: I think that the configuration files

uref = 17.3 m/s ==> k = 1.122
uref = 8.7 m/s  ==> k = 0.284





k = 1.122 m/s ==> epsilon = 4293.94

k = 0.284 m/s ==> epsilon = 546.10


epsilon = 546.10 ==> omega = 1924.001
epsilon = 4293.94 ==> omega = 3825.89

So now I have U, p, k, and epsilon covered.

CFD stuff

Step 1: run simulation with pisoFoam
Step 2: run selected time step with SimpleFoam

Make sure that you scale the mesh correctly.

Look at videos showing how to plot.
