Re: [TRNSYS-users] dynamicdata function

Amandine,
Ups, sorry for my previous email. Dave, thanks for giving us the correct answer.

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

Dear users,
a DynamicData procedure is included in Type107 code and it seems a bit different that what's described in Trnsys Programmers guide. In a handmade Type, I try to read my own file but DynamicData always give me the wrong solution. the code is the following: C GET THE PERFORMANCE DATA FROM THE S1 DATA FILE: FRACTION OF DESIGN CHILLED WATER CAPACITY C AND FRACTION OF DESIGN COP ARE FUNCTION OF INLET HOT WATER TEMPERATURE, INLET COOLING 
C  WATER TEMPERATURE AND OUTLET CHILLED WATER TEMPERATURE LEVEL

  NVAL=3
  NY=2
  NX(1)=5
  NX(2)=3
  NX(3)=5
  X(1)=TCHW_T1
  X(2)=TCW_IN
  X(3)=THW_IN
  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)
and data file is (separation = tab): 5.5 6 7 8 9 !Chilled Water Temperature output at previous timestep 24 29.5 31 !Entering Cooling Water Temperature 75 80 85 88 95 !Inlet Hot Water Temperature 0.87671 0.88571 ! Fraction of design capacity and design COP at 5.5 24 75 0.98630 0.88571 ! Fraction of design capacity and design COP at 5.5 24 80 
y1  y2    ! Fraction of design capacity and design COP at    5.5 24 85
etc...
Can someone detect the problem..? thank you for your help, Amandine LE DENN
