chtMultiRegionSimpleFoam

Hi,

As i read in the documentation, chtMultiRegionSimpleFoam is a steady-state but i don't know how to get a steady-state simulation. In my case chtMultiRegionSimpleFoam iterate over time...

Any help ?

Thanks.

You run a steady simulation by making the ddt scheme in each region steadyState. It will still iterate over "time" but it's really just the iteration number (when deltat is set to 1 in the controlDict). You can check out one of the tutorials (e.g. https://develop.openfoam.com/Develop.../heatExchanger) to make sure you've set your case up correctly for a steady simulation.
