Re: [TRNSYS-users] TRNSYS control cards

Makram,

You did a nice job with the include file, but you didn't use the names that you defined there as the names for the simulation start time, stop time and timestep in the control cards of your project.  Change the units of those three cards to string (or variable name) and specify TStart, TStop and Tstep.  See attached; a version 18 screen capture, v17 will look differently but you get the idea.

Jeff,

 

I tried your solution: I created an inc file (file.inc), I added the line "include file" to the deck file. Unfortunately, it didn't work, I don't recieve any errors and the simulation works but the values of the simulation cards don't change.

You will find attached, my deck file and the inc file.

 

Thank you in advance for your help.

Makram,

 

You can use an INCLUDE file.  Details can be found in the documentation.  The include file must also follow the TRNSYS requirements on structure.

 

So it may look like:

EQUATIONS 3

Tstart = 0

Tstop = 8760

Tstep = 0.05

 

Then these variable names appear in your control cards.  You could also put your control cards in an include file but then you have to edit the input file manually.

Thank you for your answer Jeff.

Is there a way to change control cards externaly? For example:

Simulation start time= tstart

Simulation stop time= tstop

simulation time step= tstep

 

Where tstart and tstop and tstep are given in a external file (.txt).

 

Thank you.

Makram,

 

You can use equations to set the control card variables.  For example:

 

STARTSIM= 0

DAYS= 57

STOPSIM= STARTSIM+DAYS*24

 

Then use these names in the appropriate spots in the control cards.  The only caveat is that they can’t change during the simulation.

Hello everyone,

 

Is there a way to change control cards automatically?

For example, by creating a parametr (or equation) or by calling a variable from an external txt file.

Thank you.
