Geoffrey, We have been working on some modifications to the TRNSYS code so that it is compatible with the Intel Visual Fortran compiler and will be releasing v. 16.00.0038 shortly. The problem with Access Functions that you have run into is fixed in version 0038. Because we are not ready to release that version just yet, it would perhaps be best if I make you a TRNDll.dll file with the modification to TrnsysConstants that you need in order to run your simulation. If you would please send me an email directly (dbradley@engr.wisc.edu) as well as the modified values that you would like, I would be happy to compile and link a new DLL for you.
