Hello all,
I am trying to configure fvOption to take a csv/text file for the heat source for each time step for my selected cellSet. The csv/txt file would have the 1st and 2nd column as the timestep and power (W) respectively. I was wondering if there is a way to configure fvOption in OpenFoam_v6 for this?

I would really appreciate all your help. Thanks!

Below is a sample of my fvOption file

heatSource
{
  type   scalarSemiImplicitSource;
  active true;

    scalarSemiImplicitSourceCoeffs
    {
        selectionMode     cellSet; 
        cellSet               heat_point;
        volumeMode      absolute;
        injectionRateSuSp
        {         //heat energy in Watts for each timestep
            h   (120 0) (100 0) (150 0) (200 0) (170 0);  //Watt
        }
    }
}

Hello Henry,

As far as I know it's not possible with OpenFOAM-6.
It should be possible on OpenFOAM-8 and newer versions.

For the OpenCFD branch, on OpenFOAM-v2006 and newer versions.

Regards,
Yann

Hi Yann,

Many thanks for your response. I will try out OpenFoam-8 and see if it works.

Cheers,
Henry

I regularily use Excel to reformat such data into the form to directly put into fvOptions. Then there is no need for an additional file. Lets say you have your time in column A and value in column B, insert this in C1, drag down through all your values. Select all cells in C, Ctr + C and insert into fvOptions. Done.
