Re: [TRNSYS-users] ERROR: simulation times



TRNSYS uses the units of hours of the year for simulating. When you change the units of the start and stop time in the control cards, Studio converts the numbers that you choose back to hours of the year before writing the input file. There are sometimes some rounding errors when it does so. The error you got is probably telling you that the time step is not an integer multiple of the start time. To be safe, I do not recommend changing those units.

Hi,

I'm finding some problems when i change the simulation times parameters.
I opened the SDHW example to test this. I run the simulation and it goes OK.

The parameters defined where:
Simulation star time: 3624 hr
Simulation stop time: 5088 hr
Simulation time step: 0.25 hr

Then, i go to "Assembly -> Control Cards" and change this parameters to:
Simulation star time: 1 day
Simulation stop time: 150 day
Simulation time step: 1 hr

and it appears this error message: "One error was found in the deck. Check the listing file for more informations."

Can anyone tell me what is wrong?

Thanks!
