Temperature and Velocity Limiter in rhoCentralFoam

cfdpester · September 20, 2023, 09:16

Hello,

I have included in the fvoptions file the limiter of velocity and temperature in rhoCentralFoam. It's read but not applied. I want to limit temperature and velocity to avoid the solution diverging initially. Can anyone help me?

Thanks,

Nick

Code:

limitV
{
    type            limitVelocity;
    active          yes;

    selectionMode   all;
    min             200;
    max             400;
    
}

limitT
{
    type            limitTemperature;
    active          yes;

    selectionMode   all;
    min             100;
    max             600;
}

Hello Nick, I am also struggling with the same issue!

I learned from different sources that rhoCentralFoam does not work with fvOptions. If one wants to use fvOptions, one has to modify the source code (rhoCentralFoam.C). I am not sure how to do it properly. I have to go through the tutorials.

In case if you find a way to limit the temperature, could you please post it here? Thanks you so much.
