[TRNSYS-users] InterpolateData

[Erik Boschek]

Dear David / TRNSYS-users,
 
thank you for the hint for using DynamicData. That worked and in the mean time I have upgraded to version 17.
 
I have another question about using what is now called InterpolateData. Essentially, I was wondering if it is possible to extract directly the mimimum and maximum values of the independant variables from the data file being interpolated. Obviously, values outside of these ranges are not extrapolated. Thus, it would be sometimes be useful to use those limits automatically as constraints in the logic of the component.
 
As a first try, I have modified "InterpolateData" to return an array containing all these limits - something like:
 xMinMax(1,1) = X1dd(1,ILUdd)
xMinMax(1,2) = X1dd(NX1dd,ILUdd)
.
.
.
xMinMax(6,1) = X6dd(1,ILUdd)
xMinMax(6,2) = X6dd(NX6dd,ILUdd) 
 
Is there is a more straight forward way in which I don't have to modify "InterpolateData"? Or am I missing something?
 
 
Thanks,
 
Erik

Erik,
  We found and fixed this in Trnsys17 when we moved over to the IVF compilers. CVF didn't mind if you exited a subroutine without deallocating your allocatable arrays (it deallocated them for you). IVF is a bit more rigorous and forces you do deallocate arrays manually. You need to add the following lines to the GROW() subroutine in DynamicData

Deallocate(X1TEMPdd)
Deallocate(X2TEMPdd)
Deallocate(X3TEMPdd)
Deallocate(X4TEMPdd)
Deallocate(LUSTORTEMPdd)
Deallocate(YDATATEMPdd)
Deallocate(DATAINTEMPdd)
Deallocate(IPTTEMPdd)

  Another issue that you may run into is that IVF does not like when a function returns without setting a return value. CVF was more forgiving about that. You will need to go through some of the TrnsysFunctions routines and make sure that they always set a return value. Again, this is fixed in Trnsys17.
Best,
 David
