[TRNSYS-users] dynamicdata function

[David Bradley]

Amandine,
   This is a common error. The format of the data file read by DynamicData is:

Values of X3
Values of X2
Values of X1
Data

what you used is:

Values of X1
Values of X2
Values of X3
Data

I think you need to rearrange your call to DynamicData so that it reads 
(changes are noted in bold):

         X(1) = THW_IN
         X(2) = TCW_IN
         X(3) = TCHW_T1
         CALL DYNAMICDATA(LU_S1,NX,NVAL,NY,X,Y,INFO,*10)
         CALL LINKCK('TYPE807','DYNAMICDATA',1,807)
10      IF (ErrorFound()) RETURN 1
         FNCAP=Y(1)
         FNCOP=Y(2)

Kind regards,
  David
