Caterpillar Dynasty

[ST111]

Hi I am interested in some simulation software I have heard of and read about briefly online:

http://machinedesign.com/archive/software-simulates-many-disciplines-one-model

This is used by caterpillar only, I am interested if anyone has used this before? It appears it can only be used for dynamic analysis, but does this limit its functionality? and why have they developed there own software rather than use something else? For example would someone with training on Nastran or Ansys be able to use this and vice versa (if someone used this could they transfer skills to Ansys?)
Thanks.

Did you not read the bit that says that the software does symbolic math?

Sorry I dont know what you are getting at there?

Nastran and Ansys are finite element modeling tools, which means they're inherently and fundamentally different than what is ascribed to Dynasty.

finite element modelling relies on the storage of these 'symbolic equations' (built from geometry and performance data [such as material properties]) in matrices then solving through various methods. I don't see how these are different

p.s. I am not trying to be awkward here I am just trying to understand

While both use discretized equations, Dynasty is not described as a solid modeler, which Nastran and Ansys are. The article states that Dynasty is used to generate inputs for programs like Nastran and Ansys, which makes them fundamentally different.
