Hello everyone,
Is there any function in openfoam to limit a value (density, x-velocity, y-velocity, pressure, ...) with upper and lower value at each iteration ?

I am thinking about something like the "Solution Control" + "Limits" that we can find in Fluent.


I am using the rhoPimpleFoam solver now. In my point of view, if I add a cell loop after the "solve", it will only patch the solution after all the iteration of the time step, right ?


Thank you in advance.

For the density, there is something like this :

PIMPLE
{
    momentumPredictor yes;
    nOuterCorrectors 1;
    nCorrectors     2;
    nNonOrthogonalCorrectors 0;
    rhoMin          rhoMin [ 1 -3 0 0 0 ] 0.5;
    rhoMax          rhoMax [ 1 -3 0 0 0 ] 2.0;
}

But I can't find anything for the density and the velocity (in each axis)

Edit, this is present in the "fvSolution" file
