[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
