Hello all,


My background consists of two undergraduate engineering degrees, one in electrical and the other in software.


I have been teaching myself 3D design -have about 8 apps- and am getting my feet wet in the FEA/CFD disciplines. My only application so far is the ANSYS Workbench. I downloaded the Free Student Edition. Almost all of my project's production, being Free Open Source is placed here:

The theoretical background, most of which I can barely follow is here:

BTW: additions are welcome)



Most of the material generated by my 1-person project is actually created by hired guns, aka Freelancers. For my latest challenge, I intend to perform FEA/CFD analyses and simulations of Cranium Ballistics nature in one of my models. I am told that the best tools for that purpose are ANSYS Autodyn (included with my version) and LD-Dyna (not included). The hired expert tells me that the cranium model to be used should be in one of the Parasolid, STEP or IGES formats. Regrettably, the only workflow seems to be from Maya, an Autodesk app which is supposed to be able to export all those file formats is buggy.


These are the models that I have purchased. All find identical failure during conversion. Screenshots below.

Has anybody had experience generating those file formats?



Alternatively is there any source for cranium models used for forensic FEA purposes?


What are the limitations of my Student Edition vs. the full professional package?



Any expert insight, tips, etc. are very welcome and appreciated.
