[blockMesh] Wall mounted Hump 2d

Deep111090 · July 19, 2023, 00:32

Hi All, Is there any online resource for setting up the 2D wall-mounted hump case in OpenFOAM. This is a standard case in the NASA turbulence repository, and due to my limited knowledge of mesh generation in OpenFOAM, I am finding it hard to create a blockmesh dict for the geometry. For reference i am adding the link to the case : https://turbmodels.larc.nasa.gov/nasahump_val.html

Hello,

First thing you can try is searching into the tutorials, for instance with this command:

Code:

grep -ri "hump" $FOAM_TUTORIALS

If you are using the ESI-OpenCFD branch (openfoam.com), this should lead you to this tutorial, which, luckily, seems to be exactly the case you are looking for:
https://develop.openfoam.com/Develop...allMountedHump

Unfortunately this case is not available in the OpenFOAM foundation branch (openfoam.org).

If this is the branch you are using, you could get the mesh from the link above and adapt the case to the version you are using. However if you are just beginning with OpenFOAM I would strongly recommend to install the latest version of the OpenCFD branch. Learning OpenFOAM is already time-consuming, it will spare you a lot of struggle to adapt the case to another version.

Cheers,
Yann
