extrudeMesh
 
Hello

Can anyone give a quick overview on how to use extrudeMesh utility? Or maybe point out a tutorial for it? I have been trying to get a basic instruction on how to use this utility but found none.

thanks

Greetings xiyuqiu,

extrudeMesh is very simple to use... it's usually part of more complex tutorials, such as this one: http://openfoamwiki.net/index.php/Ma...Examples/2DsHM

You can also find which tutorials use extrudeMesh by running:
Code:

find . -name "Allrun" | xargs grep extrudeMesh -sl
In addition, the reference dictionary file is located at:
Code:

$WM_PROJECT_DIR/applications/utilities/mesh/generation/extrude/extrudeMesh/extrudeMeshDict
You can look at it online here: https://github.com/OpenFOAM/OpenFOAM...xtrudeMeshDict

Best regards,
Bruno

Hi Guys,

I also have a question to extrudemesh, maybe I'm just blind and don't see the obious answer but I didn't find it yet...

I'm using openFoam 2.4 water channel example. The example works fine, but if I increase the number of cells extrudemesh is not generated. I assume that there is a problem with the nLayers but I'm not sure.

I need to increase the number of cells to get a time dependency of different solvers.

Thanks in advance for your help
Jasmin

Quick note: Please follow the instructions given here: http://www.cfd-online.com/Forums/ope...-get-help.html

I don't know if anyone else has the time to go one step a time with you, but unfortunately I don't have enough time (at least today/this week) to try and deduce what steps you've taken :( If you had been more specific with more details in your post, I might have been able to give you a clearer answer than this :(
My guess is that the output given by extrudeMesh upon execution should have been fairly clear on what went wrong.
