Nomikos, I am not familiar with the Force FORTRAN compiler. From what I read online, it is a development environment for the GNU Fortran project. In short, if the compiler is able to create a 32-bit dynamic link library then it "should" be able to generate a DLL usable by TRNSYS. I put the should in quotes because accomplishing this is often a good bit more difficult than it sounds. I would first check with the Force forum and see if their IDE can create a DLL. If so, you might get some useful information from the following tutorial: http://sel.me.wisc.edu/trnsys/downloads/tutorials_and_examples/tutex17.htm (click on the "Using G95 to create TRNSYS TYPES (English)" link) If Force is not able to create the DLL, you could use the G95 compiler (which is also free).
