Manipulating field values in a specified area of a 3D domain
 

Hello everyone,
I have a 3D hilly terrain and want to manipulate variables e.g. Temperature of a specific area inside the domain.
That mean, I want first, run my “normal” case Steadystate that the flow is developed. (That’s of course no problem)
But, afterwards I would like to change only Temperature conditions around a mountain (e.g. at the northern valley 0-50m in height (z-axis) at some specific x/y-cells inside of my domain.
Afterwards I will restart the run.

Is there any solution for that?

Yes, you can use setFields to set the temperature of some cellSet. See eg. https://github.com/OpenFOAM/OpenFOAM...akWithObstacle.
