[TRNSYS-users] Problems with Timestep

Dear Trnsys Users,

I’m having a problem while I try to run a simulation with a 0.01h time step. My radiation data is in 1 minute intervals and therefore my time step has to be smaller than that. I chose 0.01h, but I get the following error when I try to run the simulation

* START, STOP and STEP

CONSTANTS 3

START=4037

STOP=4080

STEP=.01

* User defined CONSTANTS

*SIMULATION Start time End time Time step

SIMULATION 4.037E+03 4.080E+03 1.000E-02

***** ERROR ***** TRNSYS ERROR # 203

THE SIMULATION START TIME MUST BE AN INTEGER MULTIPLE OF THE

SIMULATION TIMESTEP. CHECK SIMULATION STATEMENT.

I don’t get it 4037/0.01=403700, which is an Integer multiple of the timestep.

Any help?

Thanks,

Juan
