FluidFlow3 v3.22 Build 4 (16th October, 2011) Added back the ability to decide on the Vsm calculation method for settling slurries. Added results to text output. Expanded scripting section of the help file. Added some new PP and PPF Pipes and some new PP diaphragm valves into databases. Stopped an "Out of Resources" error occurring in the scripting window if margins were shown. Fixed a heat transfer bug that occured when 2 exchangers were used in series, with the Heat Transfer Option set to "heat transfer into network". Fixed a bug that occured if a dialog box was shown off screen.
