Hi guys,

I'm doing a research that simulates airflow over urban buildings, therefore I need to create geometries of those buildings with certain spacing.

Does anyone know the effective way of setting this up in OpenFOAM?

The figure below is the example of the simulation model I need to set up:

Hello,

have a look at the m4 programming language. With the help of this language you can create parametric meshes.

I attached a zip-archive with a m4 file and a screenshot from paraView to give you an idea what this script creates.

To use this script change type something like this:

Code:
m4 cuboidMesh_BlaBla > blockMeshDict
This command lets m4 parse the first file (cuboidMesh_BlaBla) and stores the result into blockMeshDict.

After that you simply run blockMesh.


You can play with the mesh generated by my script and place a single block in the flow.

Hello, I'm doing research about shock waves in urban area. I konw it's been a long time, but please tell me if you have succesfully run your simulation or not. What I'm doing now doesn't work......... So maybe I can use openfoam to do my simulation. Thanks in advance.
