Vensim Help

In addition to the files you install, using compiled simulations may create some or all of the following files.  These files will be created in the directory the model you are compiling is contained in.

mdl.c - the C equations representing the model.
mdl.obj - a compiled version of mdl.c.
mdlname_sim.dll ,mdlname_ simdp.dl, mdlname_asim.dll ,mdlname_ asimdp.dll - the compiled simulation program.  This is all that is necessary to actually run the compiled simulation.  A different file is needed for SyntheSim. Regular simulations, optimization and sensitivity simulations all use the same dll file.
