[TRNSYS-users] Type9 Data Read. Recursive in time

Wed Sep 19 14:22:34 PDT 2018

Jordi,

   Yes, Type9 does require that all the data entries be equally spaced 
in time.

   You can set up Type9 so that its data is not assumed to start at the 
beginning of the year but at a particular time. Have a look at the 
various modes of Type9. They are explained a little bit if you click the 
"more" button by the "mode" parameter. There is some additional 
explanation in the Type9 section of the 04-MathematicalReference manual 
and I think there may also be some explanatory examples in there.

   I suppose the best way to prevent Type9 from rereading the data file 
once it gets to the end would be to put a lot of extra values (perhaps 
zero values) at the end of the real data. I'd be a little careful of 
this and I am not clear what you would want Type9 to output if the 
simulation continues on past the end of the data file.

kind regards

  David
