<t>Thank you Ajay. I have investigated SD-Fast a bit more and discovered that the equations etc are built into a series of C-functions generated in a file when the model is compiled.<br/> <br/> I'd be interested to see what these functions look like for Simbody, do you know if a similar file (of fun...

<t>Hello,<br/> <br/> I'm trying to get to grips with understanding the differences between SimBody and SDFast as a engine for OpenSim. In particular I'm interested in the opportunity to extract equations of motion symbolically.<br/> <br/> I understand that as SD-Fast is a general purpose multibody e...

<t>Hi,<br/> <br/> OpenSim looks like a great tool though I am a little confused about the difference between using the SimBody engine and SDFast. Would it be possible for someone to summarise the benefits of purchasing SDFast?<br/> <br/> I'm really interested in extracting the Dynamic Equations of m...
