Residuals written multiple times in file with chtMultiRegion

Dear All,

I am facing a problem when using the functionObject residuals with chtMultiRegionSimpleFoam.

Here the code:

Code:

residualsFluid

    {  

      type            residuals;

      libs            ("libutilityFunctionObjects.so");



      writeControl    timeStep;

      writeInterval   1;

      region          fluid;



      fields (p_rgh U h k omega);

    }

The residuals are correctly saved in the corresponding file in the directory postProcessing but they are written three times for every timeStep:

Code:

# Residuals   

# Time          p_rgh           Ux              Uy              Uz              h               k               omega         

1.002           1.0000000e+00   0.0000000e+00   0.0000000e+00   1.0000000e+00   1.0000000e+00   1.0000000e+00   5.7152730e-03

1.002           1.0000000e+00   0.0000000e+00   0.0000000e+00   1.0000000e+00   1.0000000e+00   1.0000000e+00   5.7152730e-03

1.002           1.0000000e+00   0.0000000e+00   0.0000000e+00   1.0000000e+00   1.0000000e+00   1.0000000e+00   5.7152730e-03

Does anyone know the reason for this?

Thank you in advance.
Luca

EDIT:
I am using OF 5.x and the problem happens in serial as well as in parallel. Residuals are always written three times each.

Hello!
is it possible that you have:

nNonOrthogonalCorrectors 3;

?
