Conversion from SIMULIA to U3D is not supported yet :(

SIMULIA is a CAE suite built on the 3DEXPERIENCE® platform by Dassault Systèmes and used to create realistic simulations.

SIMULIA tools deliver various types of computational simulations (electromagnetic, computer fluid dynamic, multibody dynamic analysis, structural analysis) and capabilities to increase their efficiency (standard processes automation, logical and physical models integration, collaboration and sharing).

Universal 3D (U3D) is a compressed file format standard for 3D computer graphics data.

The format was defined by a special consortium called 3D Industry Forum that brought together a diverse group of companies and organizations, including Intel, Boeing, HP, Adobe Systems, Bentley Systems, Right Hemisphere and others whose main focus had been the promotional development of 3D graphics for use in various industries, specifically at this time manufacturing as well as construction and industrial plant design. The format was later standardized by Ecma International in August 2005 as ECMA-363.

The goal is a universal standard for three-dimensional data of all kinds, to facilitate data exchange. The consortium promoted also the development of an open source library for facilitating the adoption of the format.
