I have been using OpenFOAM for a few weeks now and all the threads on this forum has helped me tremendously. However, I am stuck know on the following issue:

I want to make a input parameter dictionary that OpenFOAM reads before running blockMesh and the solver. In this parameter file I want to define (for example) a geometry property, lets say the size of a cube used by blockMesh. How can I read the dictionary?

This thread has been helpfull:

I understand that you can read the dictionary with IOdictionary, but where do a place this code? In the controlDict?

Any help would be great!

Hello there,

I am trying to to the same! I would like to define somehow in an external directory the values of the points of blockMesh as well as the values in toposet dicts for the regions of the mesh refinement. Is there anybody with an idea how this could be achieved?

Best Regards,

Why don't you use the "m4" to make "blockMeshDict" automatically?

you can define your parameter in "m4" file (for example: blockMeshDict.m4) and then use the following command:
m4 -P blockMeshDict.m4 > blockMeshDict
check the link to find out how to use "m4":
