Re: Coupling TRNSYS 15 with IT, IHT or FEHT

[David Bradley <bradley@xxxxxxxxxxxx>]

Dear Gassem,
  Yes, theoretically you can connect TRNSYS to those programs,
although not in exactly the same way that TRNSYS is connected to EES.
Because the Solar Lab has access to both the source code for EES and the
source code for TRNSYS, they were able to write a two sided connection
between the two programs. TRSNSYS passes data to EES and EES knows what
to do with it. The same would be true of FEHT since again it is written
by the SEL. However, in most cases, one does not have access to the
source code of the second (non TRNSYS) program. There is a TRNSYS utility
subroutine called "callprogram" There is a TRNSYS Type (66)
which shows an application of using the callprogram routine to launch and
command another application. In order to develop a link with the programs
that you list below, you would have to create a new TRNSYS Type, written
in Fortran, which duplicates the function of Type66, modified as
appropriate for your second program. 
Kind regards,
  David
