Conversion from SIMULIA to X3D 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).

X3D is ISO standard XML-based file format for representing 3D computer graphics. X3D features extensions to VRML (e.g. CAD, geospatial, humanoid animation, NURBS etc.), the ability to encode the scene using an XML syntax as well as the Open Inventor-like syntax of VRML97, or binary formatting, and enhanced application programming interfaces (APIs).

The X3D extension supports multi-stage and multi-texture rendering; it also supports shading with lightmap and normalmap. Starting in 2010, X3D has supported deferred rendering architecture. Now X3D can import SSAO, CSM and Realtime Environment Reflection/Lighting. The user can also use optimizations including BSP/QuadTree/OctTree or culling in the X3D scene.
