MSX [SOURCES] limitations
Ryan Catling
Hi, The SETPOINT and CONCEN soureTypes are quite bugged in the latest version of WaterGEMS and CAD (10.04.00.108). So far I had been able to function with workarounds to the bugs but now I've encountered a point I can't figure out a workaround for…

How to set Diameter units in MSX to meters
Ryan Catling
G'day Team, Can someone please tell me how to change the MSX units for the pre-defined term 'D' from feet to meters? The MSX Manual states that Diameter can either be in Feet or Meters, however no-where does it say how to change it or what the unit…

How to include Mass Transfer Coefficient into MSX
Ryan Catling
Hi Everyone, We're currently working on developing an MSX model for Chlorine Decay that can account for wall decay as a factor of Biofilm growth (thus removing the need to specify wall decay for specific pipes throughout the network). Unfortunately…
