Steady-State velocity-field for transient heattransfer problem

lolo97 · March 4, 2020, 14:08

Hello everybody,
as I´m more or less new to CFD and mostimportantly new to OpenFoam, i have a problem, and hope some of you can help me out.
What I want to do:

I want to setup a case, just like the tutorial "windshieldDefrost" for the chtMultiregionfoam.
The problem here is, that in my case it takes ages to solve.
So from what I have read, in StarCCM+ there is an option to solve for the steady-state flow, so they have a time-independent averaged velocityfield, which then acts as an input/BC for the transient heattransfer, and used for solving for the convective heat transfer coefficient.

i now would like to know how to do that in OpenFoam, but i absolutely don´t know what to search for.

Can someone help me out?

Cheers,
lolo

Hi my friend,

Did you find the solution to the problem you described?

Please let me know if there is a way to solve windshieldDefrost in OF2012

Regards
