Fluid Structure Interaction

VPG’s ALE/FSI Module allows the engineer to create advanced ALE and SPH simulations using LS-DYNA and automatically creates ALE mesh zones and explosive pressure sources, saving time and increasing productivity.

Parametric Model Definition
The ALE/FSI Module quickly sets up LS-DYNA ALE meshes with multiple zones and blast sources using a simple parametric model definition.  Users have complete control over mesh density and blast source shapes.

Simulate Fluid & Structure Interaction
Fluid and structural interactions are quickly and accurately defined using ALE/FSI.  The user can take advantage of eta/VPG’s complete LS-DYNA element and material library to create complex structural models which interact with the ALE mesh.

Generate Graphical Data for Evaluation
VPG’s post processing capabilities allow the user to visualize all simulation results, animating the pressure, velocity and motion of the results.  Graphical data may also be displayed to provide an in-depth evaluation of the simulation results.
