[TRNSYS-users] Changing start time e.g. in RadiationProcessing.tpf

Dear Trnsys Users,

I get an error when I change the start time of a file including a Type 9-Type 16 radiation processing combination (as e.g. in the Trnsys example file RadiationProcessing.tpf).

Everything works fine with ‘Simulation Start Time = 0 hr”

But with ‘Simulation Start Time = 1 hr” I get an error at hour 9 of the simulation

*** Fatal Error at time : 9.000000

Generated by Unit : 4

Generated by Type : 16

Message : The simulation timestep is greater than the data timestep for the radiation calculation. The simulation timestep needs to be reduced.

And with ‘Simulation Start Time = 12 hr” I get the error :

*** Fatal Error at time : 13.000000

Generated by Unit : 4

Generated by Type : 16

Message : The simulation time is outside the data reading interval. If you are using a combination of Type9 and Type16, make sure that Type9 outputs 99 and 100 are connected to the appropriate Type16 inputs.

Does anyone has a suggestion?

Kind regards,

Maarten
