Latest Release


What’s new in 2021

New Features

  • Simpack/XFlow co-simulation: newly implemented co-simulation workflow. It is now possible to:
    • Effortlessly import Simpack setups in XFlow.
    • Automatically setup XFlow/Simpack co-simulation runs (several options available, e.g.
    • Simpack Rigid 2-way | Simpack Rigid kinematics).
    • Execute the entire co-sim workflow directly from the XFlow GUI.
  • Abaqus 1-way deformations: It allows exchange of displacements from Abaqus to XFlow but no forces are sent from XFlow to Abaqus. This option is relevant when forces from XFlow are negligible for the Abaqus setup.
  • Co-sim orchestrator: enables generation of co-simulation configuration files (both from XFlow GUI and command line) and manages the co-simulation execution.
  • Hole filling tool: to repair geometries with holes, creating a lid geometry to close the holes.
  • Co-simulation pressure limit: to cap maximum pressure values sent in co-simulations.
  • An executable named xflow_numericaldata_export is available to extract numerical data from simulations into a tabular data file without opening the GUI.
  • Export numerical data available under the Simulation data menu to extract an arbitrary set of numerical data from the Function Viewer.
  • Seal small gaps feature: enforces the domain generation for geometries that have holes /gaps smaller than the resolution. Useful to reduce the geometry preparation time.
  • Volumetric rendering and surface info now show a progression bar during the rendering process.
  • DSLS stat tool: lightweight executable that checks DSLS license availability.
  • Geometries can be renamed using the F2 key.
  • The XFlow logo color in the Graphic View can now be changed


  • Abaqus/XFlow co-simulation: co-simulation configuration file can now be generated from the XFlow GUI.
  • Co-simulation with Abaqus using small size geometry are now much faster.
  • Improved Abaqus/XFlow co-sim synchronization handler: more robust implementation that supports arbitrary negotiation time settings (e.g. multiple of XFlow timestep).
  • Updated CSE libraries to CSE 2020HF1 and inclusion of libraries in installer.
  • The .bat files in Windows are now using a relative path.
  • Post-processing speed of iso-surfaces, markers, and volumetric rendering has been improved in some cases.
  • The stability of the pressure outlet boundary condition has been improved in the Phase Field solver.
  • Surface field distribution color has been changed to black and white color for a better visibility.
  • License specification file to point to the license server can be defined with environment variable and a new SimuliaLicenseConfig.txt file.
  • Hole filling tool additional options and improvements:
    • Output of healing process can be selected to be only the closing Patches or a solid Wrap
    • Created patch geometries can optionally be split in individual shapes
    • The perimeter of each patch can be extended normal to the original geometry set used
    • The geometry set bounding box can be used as a support shape to improve stability of the hole filling process
    • Add by mouse option for inner entities (either points and spheres)
    • Inner points initialized with CoG of geometry set
    • Minimum and maximum size parameters for Mesh definition are initialized accordingly to geometry set bounding box
  • Stability improvements for the air compressibility in the multiphase particle-based solver.
