[TRNSYS-users] Type 534 Inlet Flow Mode 3, GenOpt

Hoofar - I’m not sure why you chose inlet mode 3 for the tank. That mode signifies that the location of the inlet port changes with time such that the stratification is preserved. I have used that mode once in my 30 years of using TRNSYS - and I do a lot of tank modeling. That was a tank that had a strange umbilical float that tried to have the water enter the tank in the ideal location.
But either way, you are not forced to use the plug in. Simply take one of the existing full proformas and modify it to match your tank parameters. We provide a few examples of different full tank proformas but there are thousands of possibilities so we don’t provide all of the options.

> I am using type 534 tank for stratification. As the inlet flow temperature to the tank is not defined and varies over time, I have to use „INLET FLOW MODE = 3”. However, changing this parameter is not possible in without plug-in type (as it is locked). At the same time, I am running an optimization using GenOpt and one of the optimization parameters is the volume of the tank. The problem is that in type 534 with plug-in, I can not choose the volume as parameter which changes by each GenOpt run and just fixed numbers can be used in plug-in. How can I resolve this problem?
