Hello
I've been trying to change the parameters of simpleGrading in the mesh file so that I get smaller quadratic orthogonal elements near the edges. However, I seem to only be able to make them refined on one side. I just have a square cross-section that I would like to refine at the edges. Thank you very much Kind Regards, F |

Apologies for the noob question, but where do I put the folder that I just downloaded?

In principle any where, but I like to put it in OpenFOAM/user-2.0.x/applications/utilities/. After you extracted the files, run the Allwmake script once and then you can use the utility.

What happened exactly when you ran ./Allwmake? What was the error message if you got any? Were you able to run any other OpenFOAM commands in the same shell?
The executable name is "blockMeshDG" by the way - the capitalization is important.

Ok it compiles now.
What is the required syntax for having inflated meshes at each side of a square? simpleGrading I suppose would not incorporate this effect? Kindest Regards, Francesco |

Use it just like the standard blockMesh, but use negative coefficients where you want double grading.
