DualSPHysics v4.0 released

The DualSPHysics team are pleased to announce the release of DualSPHysics v4.0 that includes the C++ and CUDA source files of the SPH solver.. 


To download the DualSPHysics package, documentation and source files, visit the DualSPHysics website

There, you will find these new files:

    • DualSPHysics_v4.0_GUIDE.pdf
    • XML_GUIDE_v4.0.pdf
    • PostprocessingCalculations_v4.0.pdf
    • ExternalModelsConversion_GUIDE.pdf

 News in the current release:

  • Source files with GPL license.
  • Complete documentation using Doxygen.
  • New CPU structure that mimics the GPU threads.
  • OpenMP is now optimized for execution in multi-core CPU machines; an efficiency of 94% is achieved using 32 cores.
  • New automatic estimation of the optimum block size of CUDA kernels.
  • Implementation using double precision where necessary.
  • Improved formulation for adding external forces (now includes all relative rotational acceleration terms)
  • A prescribed movement can be loaded from an external file with defined rotation time series like already exists for translation.
  • Source files of the coupled SPH & DEM.
  • Executable of the Multi-Phase code for soil-water (source code to following v4.2)
  • Novel Shifting algorithm.
  • Automatic wave generation (regular and random waves).
  • More powerful GenCase.
  • The new postprocessing tool ComputeForces is provided to compute the force exerted by the fluid onto a solid object (fixed or floating
  • The new code FloatingInfo allows to obtain different variables of interest of the floating objects during the simulation; positions of the center, linear velocity, angular velocity, motions (surge, sway and heave) and angles of rotation (pitch, roll and yaw).
  • New version allows user to define intervals of time with different output time to save results.
  • Post-processing tools are now designed to deal with variables defined by the user.
