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
