computing the total dpm mass in a selected fluid volume.
Client is interested to see the mass of particles in each of the three tanks after a certain time.
As he has 3 different fluid zone the default dpm summary is not giving the mass in each individual
Client needs to define the fluid volumes of three tanks in gambit as FLUID.
The zone can be identified in fluent as say tank-1, tank-2, tank-3.
Client can define a custom field function as a product of DPM concentration
and cell volume. This custom field function will give the dpm mass in each cell.
Client can do the Report-->Volume Integral --> Sum of custom field function
and select the appropriate fluid zone.
