Hi,  
I’m going on with DLL related work in FAST. I partially implemented part of the work as per this previous post

[url][FAST feature request](http://forums.nlr.gov/t/fast-feature-request/349/1)]

After the test of various combination of OS/compilers/prog-languages actually I’m quite satisfied with following (peculiar is that is free)

- Linux OS (Fedora distro)
- Intel FORTRAN Compiler for Linux
- custom BladedDLLInterface …( the external library could be C or FORTRAN, actually C cause I’m more proficient with it)
- “very” custom FAST build, this allow for:
  1. custom DLL,procedure specified in the primary input file and not hard-code at compile-time)
  2. real-time simulation with external hardware-in-the-loop (if required external condition are met, as speed of the overall system/communication )  
I added an option to “slow down” sim to stick to real-time, if somehow the sim is already slower or near real time thi feature is unusable

PS: differently from CENER I link and load dinamically also on Linux

TODO

- feed aerodyn with a real wind coming from external controller (will be hh wind of course)… this is really interesting for me! is this possible? I’m studing the aerodyn interface
- as usual, explain a little better with a blog article on my page
- turn code OS/Compiler independent (that thing about ISO\_C\_BINDING I mentioned before) !!!

all these things basically allow me to use FAST-RT (as I refer to for distinguish from normal FAST) as a simulator for real turbine controller… trying to emulate what Bladed does

maybe I’m missing something else I did in the development process… but as a philosophy I tryed to change the minimum in the original code  
maybe someone else is interested and maybe the features can be implemented in a future release… when the time come

cheers, as usual  
ste
