Hi Foamers,
I simulate a ship propeller by using OpenFoam .I have case files for the propeller in real size and initially approach to the results .Now, I need to scale the propeller in model size with specified scale.
Would you please let me know how to scale the files to obtain case file for the model.

Hi Reza,
If you have a mesh file and you want to scale the geometry you can use (-scale)
for example if you have a (.msh) file you can use :

Code:
fluentMeshToFoam filename.msh -scale 0.001
Actually this code scales the geometry.

hope this helps,
Sasan.

Hi Sasan,
The mesh generated by pointwise and the exported file into Openfoam are as polymesh in constant .

Hi
the utility you are looking for is called:

transformPoints

type in the terminal

transformPoints -help

to get the correct usage and available options.
