[TRNSYS-users] Two instances of a type in one simulation

[David BRADLEY via TRNSYS-users]

Christain and Maroun,
  I would be very careful about workarounds. If you run a simulation 
that has one instance of a component in it, then drag out a second 
instance and the results of the first change then it is almost certain 
that the Type was not programmed in such a way as to allow there to be 
multiple instances in a simulation. They are sharing some data 
structures internally and there isn't really any way of getting around 
that except if you use a compiler to make a copy of the Type, give it a 
new Type number, then recompile and link it into its own DLL.
  In general the better solution is to be in contact with the author of 
Type399 (or with the distributor from whom you purchased it) and see if 
they can assist.
kind regards,
  David
