IVRESS is a simulation software product that offers users an integrated virtual reality environment. It's an object-oriented VR toolkit that's designed to enable developers to create immersive interactive worlds. While this might sound like a lofty goal, IVRESS comes with an extensive library of prebuilt objects that can make this a much easier task. Convenient selection and manipulation tools give users the freedom to select any spatial and planar areas they wish. Photorealistic rendering features like texture mapping and transparency make it possible to model fairly realistic scenes. Once you've finished building a VR environment with IVRESS, you can use the spatial navigation control to fly through the scene. This means you'll be able to view models from every side. R&D teams that modeled scenes in older software can import VRML 97 and PLTO3D objects instantly. Those who are starting from scratch can take advantage of the flexible multibody dynamics tool. It's ideal for modeling anything with joints, cams, or gears. Other geometric modeling features include boundary-representation and a native object-oriented scripting language. Support for finite element objects and CFD visualization make IVRESS a well-rounded program that engineers can use to study fluid and gas interactions. Technicians can draw an object and then run a fluid dynamics test on it. The built-in CFD simulation software will then automatically build a number of visualization objects based on the test, which include:

  • Vortex Cores
  • Separation & Attachment Lines
  • Stream Objects
  • Volume Shading
  • Elevated Surfaces
  • Volume Arrows & Particles
Even if you don't conduct a large-scale CFD study, IVRESS includes a large number of visualizations that should appeal to anyone analyzing scientific data. Dynamic data sets allow you to see how things might change over time when a system is exposed to different forces. IVRESS will automatically shade different surfaces to illustrate stresses, strains, and deformations on a structure. This makes it an attractive option for aerospace engineering teams that need to see how a prototype airframe could stand up to the rigors of flight. Advanced modeling and simulation features include 3D streamline and streakline plots, which can illustrate the flow of a particular fluid across an object. Engineers can create a custom widget or chart from any data set, so you'll be able to easily interpret the results of any simulation you run. IVRESS could even be used to create a virtual training simulator. While IVRESS is designed to run on a custom proprietary platform, it includes a browser plug-in so you can replay scenes on almost any computer. IVRESS is compatible with a large number of input devices, including:
  • Haptic Gloves
  • Position-tracking Wands
  • Head & Body Trackers
  • 2D & 3D Mice
  • PC Keyboards
Different industries have vastly different requirements when it comes to building three-dimensional VR worlds, so the app's developer isn't able to offer standard subscription packages. Interested parties are encouraged to contact them for a free quote. The IVRESS/Player plug-in is free, so it should be easy to distribute any VR environment you create to your clients. Whether you need to study fluid dynamics or test experimental aircraft, IVRESS has a VR library that can help you create models in no time.


High-fidelity time-accurate modeling of structures, multibody systems, granular materials, and fluid flow.

DIS is a general purpose explicit time integration finite element code. The following modeling techniques are seamlessly integrated into DIS:
  • Rigid multibody dynamics.
  • Finite element Method for modeling flexible solid bodies, including: thin beam, shell, spatial beam, brick, and tetrahedral elements.
  • Discrete element method for modeling granular cohesive and non-cohesive materials.
  • Smoothed particle hydrodynamics for modeling fluids.
  • Molecular dynamics.
  • Ray tracing.
