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

David,
Thank you for your reply. I have been in contact with the author of Type399, as you suggested, who sent a recompiled .dll file with a new type number. However, when running the simulation, TRNSYS cannot find the new type in the dll libraries (error message 105). I also tried to rename the dll file to "Type3399.dll", which is the new type name.
I suspect that the source code was not adapted properly to the new type number. I have the .f90 source code. Is there any way for me to compile it myself? I tried using the following guide with the free g95 compiler, but I get errors. Maybe this guide is only for fixed format .for files?

Any help would be greatly appreciated :)

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

​Christian,
I met almost the same problem two months ago, and I have solved
hardly. I don't know how can I show you through email, if you could
mail me your project and your PCM components to compare it with mine
then to fix it for you. If there any problem with you PCM component,
I'll make you know, if not I'll fix the problem the same way I've
done.

Dear TRNSYS users,
I have a multizone building model, where I want to use two PCM
components (Type 399) to model the ceilings of two adjacent rooms.
When I run the simulation I noticed that the two components
somehow share information. The PCM temperature is the same in both
components.

I tried to switch the component order in the Control Cards, which
changes the PCM temperature, but they are still equal.
How can I run two instances of a type side-by-side? Is this a
limitation in how Type 399 was programmed?

Best Regards
Christian
