Daniel, I tried it out
quickly it and seemed to work to the point where DYNDATA tries to read the data
file (I don’t have one, so I didn’t check further). It looks like it is
called correctly. Are you sure your data file is OK? It may be a good idea
to remove the last argument. It is optional and implements a jump; with your
setup, it would mean something like “GOTO 0” – no idea what
happens in this case. You could try to replace extern "C" __declspec(dllimport)
void _cdecl
DYNAMICDATA(int* lu,int*
nind,int nx[],int*
ny,double x[],double
y[],int info[],int*
n); by extern "C" __declspec(dllimport)
void _cdecl
DYNAMICDATA(int* lu,int*
nind,int nx[],int*
ny,double x[],double
y[],int info[]); (That’s what I
did in my test). If the problem
persists, you should ask one of the FORTRAN gurus to try out our data file in a
FORTRAN version. Good luck, Werner De :
Daniel.Kiehlmann@csiro.au [mailto:Daniel.Kiehlmann@csiro.au] Hi Werner, Thank you for your
answer. I checked it and I
know that the dynamicdata function is causing the error in TRNSYS. I send you the
function of the TRNSYS header file and the part of the code where it calls the
that function (it’s the example which is explained in the TRNSYS manual). extern "C" __declspec(dllimport)
void _cdecl
DYNAMICDATA(int* lu,int*
nind,int nx[],int*
ny,double x[],double
y[],int info[],int*
n); ... int nind = 2;
int nx[2];
int ny = 2;
double x[2];
double y[2];
int n=0; ...
nx[0] = 3; //3 values of second variable in file
nx[1] = 2; //2 values of first variable in file
X[0] = T_evap;
//input1
x[1] = T_cond;
//input2
DYNAMICDATA(&logical_unit,&nind,nx,&ny,x,y,info,&n);
xout[0]=y[0];
xout[1]=y[1];

[mailto:werner.keilholz@cstb.fr] Hi Daniel, It it hard to tell
without looking @ some code, but I would bet on some argument type mismatch, or
array size mismatch (your arrays must match the constants in
TrnsysConstants.f90). The TRNSYS kernel
functions mainly want arguments passed by reference, like in int a; doit(&a); Set a breakpoint on
the line that calls the function , F5 in DevStudio, navigate to Trnsys.exe,
point to the deck to run, inspect the variables when the breakpoint is hit. F11
will basically debug into the TRNDll by using the debug version (you need to
recompile TRNDll with a Fortran compiler). Hope that helps (a
little), Werner De :
Daniel.Kiehlmann@csiro.au [mailto:Daniel.Kiehlmann@csiro.au] Dear all, I’m trying to create a new component
in C++ with a dynamicdata function. It works when I build the solution in C++,
but pulls out following error when I run this component in TRNSYS: “Access violation at address 100048CC
in module ‘TRNDLL.DLL’. Read of address 00000002” Does anyone has some experience in using
the dynamicdata function in C+ and can help me out? Thanks very much in advance Daniel Kiehlmann |
