Hi All,

I am using modified version of scalarTransport tutorial, where my field of interest is biomass. I ran my simulation to 10 time steps. Now I would like to plot total biomass at each time step, i.e sum of all values at each grid point for each time. Could you please provide some hint or show me an example?

Thanks.

Hi,

You can try cellSource function object ($FOAM_SRC/postProcessing/functionObjects/field/fieldValues). See controlDict there for example, though you need to change volAverage operation to volIntegrate. For the list of available operations see $FOAM_SRC/postProcessing/functionObjects/field/fieldValues/cellSource/cellSource.H.

Thanks, I will try this.

I found the following code on this site. This code calculates volumeIntegral and write result in my log file. How can I make these values available in paraview? I am also not sure if my fields variable is correct. Do I need to define new field to hold volume. My source is definitely X.
