Particleworks for Ansys is an interface option for coupling simulations between liquid simulation with large deformation of free surface by Particleworks and various simulation fields calculated in Ansys. By using this option, Particleworks is embedded in Ansys Workbench and this makes it possible to simulate complicated multiphysics behaviors including liquid-structure, liquid-thermal, and gas-liquid flow which had been difficult to analyze, by coupling with Ansys simulation capabilities. Particleworks for Ansys is a new tool for encouraging to understand realistic phenomena in design problems.

Benefits of MPS:
Moving Particle Simulation Method used in Particleworks
- No need to set the analysis region in advance. The particles themselves represent the flow of fluid. This is optimal for tracking conditions where fluid droplets are widely scattered.
- Easily modeling of the fluid parts with CAD data of the walls, even for containers and piping of complex shapes. Only the initial particle spacing needs to be specified. Particles are evenly distributed according to the specified spacing.
- No abnormal termination and mesh collapsing issues.
