[TRNSYS-users] Initial value for outputs

[Jeff Thornton]

Ghady, 

You wrote "In order to add the initial value outputs in the Type 164
code, I prefer to create a new type and not modify the existed one in
Trnsys Library. For that I created a new component using Trnsys 17. I
had some difficulties because it's not the same code writing from
defining inputs, outputs and parameters to storage; I managed to copy
the code line that I am interested in but the problem remains with the
storage array.> 

Unless you want to completely re-write a version 16 component in version
17 format (and you are certainly willing to attempt that if you'd like),
I would suggest that you leave it in version 16 format and just change
the output initialization line as I suggested earlier. Find the lines: 

!set initial output values
OUT(1:NO)=0.d0

and replace them with your initial values:
Out(1) =20.d0
Out(2) = 0.do
etc.

Jeff
