scaling a mesh generated by gmsh

mb.pejvak · September 26, 2019, 04:43

I want to scale a grid generated by gmsh to use in OpenFoam, but using

Code:

gmshToFoam -help

does not show there is option for scaling while converting. I can modify the .geo file, but when I do it I got some error while converting, otherwise it converted without any error. Is there any way to do what I explained?

The problem arises from convering geo file to msh file with version 4. it should be done instead with version 2.

By the way there is an OpenFOAM utility for scaling a mesh, e.g.

Code:

transformPoints -scale "(1 1 1)"

You can use this after you convert the mesh to foam.
