What's New in Particleworks 7.2 글 편집

New Feature and Improvements

User Interface

  • Added RecurDyn Wall import to Viewer API, Python API

Pre-processing and Post-processing

  • Added the option to create the same results of the previous version. (Particleworks 7.0/Granuleworks 2.0)
  • Added the Pressure Boundary


  • CFD with Lattice Boltzmann Method
  • Two-way Thermal Fluid Co-simulation between FFlex Thermal and Particleworks
  • Heat transfer calculation by Heat transfer coefficient between polygon walls and particles.
  • Finite Volume Method enhancements
  • Speed up Multi GPU computations in a single process

Pressure Boundary

Two methods of pressure boundary have been added.

  • Pressure mode: Specify the pressure directly on the boundary
  • Tank mode: Apply Hydrostatic pressure in the tank as the pressure boundary

Speed up Multi GPU computations in a single process

  • When using 4 GPUs, the calculation speed is improved approximately by 2 to 3 times compared to using 1 GPU.

Finite Volume Method enhancements

  • Improved FVM analysis speed compared with the previous version
  • Enable you to use the linear upwind differential scheme in addition to the first-order upwind differential scheme in FVM analysis
  • Enable you to use the pressure boundary addition to velocity boundary as FVM boundary
  • Enable you to choose either the free outflow or the pressure boundary at the analysis domain
  • The free-slip condition between polygon walls and FVM grids in addition to the no-slip condition is available
  • Both steady-state analysis and steady-state and transient successive analysis in FVM analysis are available

Two-way Thermal Fluid Co-simulation between FFlex Thermal and Particleworks

When using Particleworks version 7.2 or later, it is now possible to use a bidirectional heat transfer function between the RecurDyn FFlex (flexible body) and the Particleworks MPS particles (fluid particles). The Heat Transfer Coefficient (HTC) calculated by Particleworks and the temperature information of the fluid are exchanged with the temperature information of the flexible body of RecurDyn according to a set time interval. Each temperature condition is used as a boundary condition for the heat transfer analysis of the fluid and solid. The two software send and receive information in the two-way communication through a dedicated interface. This feature predicts the cooling and heating of the body by the fluid and the corresponding expansion and contraction of the body structure.


The heat transfer of a moving body in close contact with the fluid and its thermal analysis can be predicted through simulation. In particular, it is now possible to visually predict and understand how a body in a high-temperature state is cooled by the surrounding fluid.
