Use the following command in the .geo file and give a try

Mesh.ScalingFactor=0.0254;

No luck with that. I got an error when I opened the .geo in gmsh. I also tried putting it in the .msh file but gmshToFoam didn't like that either. Does it have to be in a specific location?

Hi William,

you might try the transformPoints utility:
Convert your mesh to OpenFOAM. Than call
Code:
transformPoints -scale "(0.0254 0.0254 0.0254)"

I don't have any problems if i add it in my .geo file. Try adding it to the first line of your .geo file code and then remesh and save the mesh.

You will find the converted mesh. But the .geo file doesn't change its coordinates.

You can also try what Mr.Martin said. Even that works well
