Optimal FSI Solution for System Analysis

How do you solve an FSI (Fluid Structure Interaction) problem? Especially, a system dynamic analysis with fluid and co-simulation requires a high level of expertise, time, and cost for CAE, MBD, and CFD. RecurDyn provides an interface specialized for co-simulation with CFD software, Particleworks, to easily solve this challenging FSI problem.

*FSI (fluid structure interaction) is also called, 'coupled fe cfd' or 'fe cfd coupling'



Features

  • The world's first interface specialized for co-simulation between dynamics analysis and fluid analysis

         RecurDyn x Particleworks interface for easy FSI (Fluid Structure Interaction)

  • Fluid creation with meshless particle method using Particleworks        with msh-based CFD - FSI is not easy
