Hello Everyone,
I’m, currently dealing
with the development of a new type, but not in the
Fortran-based official way.
Up to now, I have
developed several Types in C++ using information from
templates that come included in the program folders, and
some imagination.
For the moment, things
went well this way.
But now I want to solve
a differential equation calling the built-in routine
SolveDiffEq(AA, BB, TI, TF, TBAR).
I may develop my own
Finite difference scheme and go on, but I’m trying to take
advantage from that kernel subroutine.
For the moment I have
not found the right way (if it exists) to include the
routine header in Trnsys.h, for later compiling and running
in the generated dll. I guess It should be this way, but it
doesn’t’t work when running trnexe.
extern
"C"
__declspec(dllimport)
void
_cdecl SOLVEDIFFEQ(double aa, double bb,
double* INIT_VALUE,
double* END_VALUE,
double* AVG_VALUE);
If anyone has the same
concerns, we may interchange information about how creating
& compiling Types this way, without purchasing an IVF
license. I will be very pleased to share my work.
Thanks in advance
Regards,
