[TRNSYS-users] Type 512 (TESS): Mass balance warning message

[Flynn Ciaran]

Hello,

I am running my simulation with a type 512 heat exchanger and I get the following warning message (no convergence errors, just warnings) at the end of my simulation (time step: 0.1 hour):

*** Warning at time       :     39384.000000
    Generated by Unit     :    45
    Generated by Type     :   512
    Message               : Heat exchanger mass balance failed during 112810 time steps. Please check the connections.

I do not understand what could be the reason for this. I have gone through my connections and they all seem fine (I do not get this problem with heat exchanger type 91).

Thanks for your help,
Ciarán
