inflated quadratic element mesh

fferroni · February 8, 2012, 03:57

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?

Rgds,

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.

Hi.
I did as you said, and put the blockmeshdg folder in applications/utilities and then ran allwmake from the folder but it told me the command didn't exist. i also tried wmake but it failed.

ideas?

Kindest regards,

F

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.

Awesome.

That works very nicely.

Thank you very much.
