Hello Foamers,
To start with heat transfer problem, I took a simple channel flow in which I know the Nusselt number variation along the wall (it changes along the length and then becomes constant). I want the similar plot from my simulations, is there any easy way of doing this in OpenFOAM v 1906, I am using "buoyantSimpleFoam" solver. I tried to look at the previous threads available in CFD Online forums like:
Code for Nusselt number
but I am unable to locate the "wallHeatFlux" utility in postProcessing or at the location
Code:
utilities/postProcessing/wall/wallHeatFlux
Is some thing different needs to be done for the OpenFOAM v1906 version ? Or is there any direct postProcessing utility available in the newest versions of OpenFOAM. Any suggestion/comment will be a great help. Thanks!
