Hi!


I am running a simulation in OpenFOAM using the interFoam solver.
During my simulation, the velocities in the air fraction become unrealistically high. Since these effects are tampering my time step, I'd like to limit the velocities in the air fraction artificially by using the limitFields function in my controlDict.


The only thing is, that when I set a limit for the velocity field, both the velocity of my air and water fraction is limited. I use the following:

    limitVelocity
    {
         type limitFields;
         libs ("libfieldFunctionObjects.so");
         fields (U);
         writeControl    adjustableRunTime;
         writeInterval   10;    
         limit both;
         min 0;   // Set the minimum value for the velocity magnitude
         max 1;  // Set the maximum value for the velocity magnitude (adjust as needed)
    }

Is there any way to limit the velocities of only the air fraction in my model?
If another function than limitFields is more suitable, please let me know as well.


Best,
Bas

I only could get it running for openFoam version 1812.

It does work with openfoam 12 as well in fvModels entry. But I dont see any changes in the velocity
