fieldMinMax is omitting certain fields

javihernandez · May 11, 2023, 07:28

Hello!

I am trying to track the position of the shock wave in a shock tube front using the rhoReactingCentralFoam solver. One of the fields this solver returns is normalisedGradP which locates the shock wave front.
I added a function of the type fieldMinMax to controlDict as follows:

Code:

libs ("libfieldFunctionObjects.so");

functions
{
    shockWavePosition
    {
    type fieldMinMax;
    libs ("libfieldFunctionObjects.so");
    fields
    (
        normalisedGradP
        p
        U
    );
    mode magnitude;
    writeControl adjustableRunTime;
    writeInterval 1e-6;
    }
}

After the simulation is run, the postProcessing folder contains the information of the maxima and minima for the fields p and U. However, there is no trace of normalisedGradP.
Does anyone have any clue why this might be happening and how to solve it?
Thanks!

Javier.

Have you solved it yet?

Have you looked in the log of your solver?

Is the fieldMinMax calculated before calculation of normalisedGradP?
