[TRNSYS-users] Linking to the TRNSYS DLL

[Steven Long]

Diego,

I'm making this change for SRCC.  We run a separate front end program that
runs 1000s of simulations in batch mode using a separate piece of software
that handles many things that support ratings generation.  As such, I need
to be able to use our existing software, which I had running TRNSYS 15, and
just need to be able to have it run TRNSYS 16.  In TRNSYS 15, with a
different compiler, I just used one line item for the DLL import and had no
problems importing, but now I'm running into the external reference error.

Thanks,

Steven Long, P.E.

Dear Steve,

I have created applications that modify the input file, and then call 
the TRNExe.exe. This alternative allows you to keep all the capabilities 
of TRNSYS.
Please let me know if this alternative works for you, as I can elaborate 
more on how to do that.
Best regards,

Diego
