Innovation Starts Here.

Inventium’s FSI application allows the user to create advanced fluid-structure interaction simulations, automatically creating ALE mesh zones and explosive pressure sources. For use with the finite element software LS-DYNA®, the user can quickly set up LS-DYNA® models with multiple fluid zones and variable charge shapes using a simple parametric model definition.

Element & Material Library
The system includes a complete element and material library to create structural models, which interact realistically with fluid models. Inventium provides easy to use tools to efficiently define these parameters, as well as the fluid-structure interactions.

Post-Processing Capabilities
FSI Simulations require special tools to aid in the visualization of the data. Inventium provides an extensive set of tools that engineers can use to view the simulation results, assess both the fluid and structure behaviors and plot the simulation results. Fluid motion and pressure visualizations and structural deformation and stress visualizations provide the information necessary to interpret the simulation results. Curves of various responses can be created directly from the simulation data.

Inventium provides this in a customizable environment which can display multiple models and results in a single instance of the software, allowing the user to query and compare several simulation results simultaneously.
