Hi,
Use a Join data set with the time-dependent solution data set as both Data 1 and Data 2, picking time = 1 for Data 1 and time = 0 for Data 2, for example. Use the default combination method, Difference, to create a data set that is the solution data (t =1) - solution data (t = 0). Then use the Join data set in the plot group where you plot the concentration.
