Re: [TRNSYS-users] 96360 hours problem ?

Sorry about the message, it was my fault : my simulations were made using a demand modeling that lasts only 96360 hours. I modified the files (equations) and everything is fine.

So this is not TRNSys’s fault.

Clement,
Can you send the text of the error message that is being written to the *.log or *.lst file?
Kind regards,
David

Dear users,

I am successfully running simulations (CSHPSS simulations) on TRNSys but recently i tried to incrase the simulation time to more than 10 years (87600 hours). At 96360 hours, a parameter stops to get its value and my simulation is false after that time.

I isolated the problem and it comes from the modelisation of the demand : I am using « equations » to model the demand and the flow rate of the demand (on the outside of the heat exchanger) is calculated thanks to the Power and Temperature difference : Flow = Power / Cp / Delta(T)

Moreover, if stating START=96000 and STOP=1752000, the same problem occurs at 96360 hours.

Has anyone had the same problem and does anyone know how to solve it ?

Many thanks,

Clement Rebillard
