time dependant simulation: variable input

Please login with a confirmed email address before reporting spam

Hi everybody,

I am trying to simulate and validate an air solar collector model. I would introduce time-dependant (hourly time step) input for air temperature and solar radiation using an interpolation function but running the simulation some errors occur (see attached file).

I set the unit in the interpolation function branch: argument=s; function=K (e.g.) and use the name function wherever I need recall it as: name(t).

Could someone help me?

thanks in advance, Giuliana.

Hello,

if you are getting this error while running stationary solver, it probably doesn't understand the time variable t, so it helps, if you define t as a parameter and set it to zero; time-dependent solver will ignore that fact.
I am not completely sure, but you coud try that.
