A relatively new standard called Functional Mockup Interface (FMI) provides a unique approach to standard models. The Model Exchange approach relies on already compiled models, thus eliminating the difference in behavior due to different implementations of the language compilers. This leads to much better interoperability, while sacrificing some of the flexibility (you cannot modify the equations in a generated model). For details about this new standard, please visit fmi-standard.org — there are an ever increasing number of tools that support this standard.
The ANSYS 15.0 systems products include support for this new standard. Read more: http://bit.ly/1cmrBQ2
