[TRNSYS-users] TRNFlow Cs, Simulink integrated with TRNSYS and Matlab 2010a DLL

Mon Oct 10 06:33:22 PDT 2011

Dear all,

I have some questions about TRNFlow and Calling Matlab.

1) For Closed Opening in TRNFlow: There is a flow coefficient Cs per m crack
length, when I set Cs as 0 kg/s/m at 1 Pa, BUT I found there is still air
flow escaping from the zone (there is only one zone in my project). Because
I observed CO2 concentration is still decreasing all the time after closed
all the openings.

2) For Calling Simulink: Which experts have some experience for calling
Simulink? I designed a Controller using Simulink, I need connect the
controller's output and input with the TYPE 56's input and output, and set a
set-point value using Simulink. Who could tell me some general guides or
give me your examples about that.

Or could I translate Simulink into M-file, then connect with TYPE 56?

3) Could you have Matlab 2010a DLL? How can I call Matlab 2010a? Which
folder of TRNSYS need I copy Matlab 2010a DLL?

Many thanks in advance!

Br

wang
