output Output

The Output Panel controls the types of data that get printed to disc and the frequency of that data for visualization and analysis. This output data includes statistics, two dimensional slice data, three-dimensional volumes, checkpoint files, and forces on static and moving bodies. It also contains particle properties.

Note

Particle output files are printed at the same frequency as output slices.

  • Statistics: The statistics tab shows which text-based simulation data (such as forces, concentrations, temperatures, velocities, and blending results) will be written during a run.

  • Planes/Probes: The output planes tab control the timed and conditional export of visual simulation data (such as VTK slices, planes, particles, and free or moving surfaces) to support real-time animation and post-processing of flow and transport behavior.

  • Volumes: Output volume controls when full-domain volume data are written, using time-based or conditional triggers to balance file size, disk I/O cost, and temporal resolution during post-processing.

  • Fluid: Output fluid defines the volume-of-fluid (VOF) isosurface contour value used to extract and visualize the fluid interface in the simulation.

  • Static Bodies: Output static bodies controls the calculation and export of forces, time-averaged forces, wetted area, and wall-function metrics on static geometry, with optional diagnostics that increase mesh and memory requirements.

  • Moving Bodies: Output moving bodies controls the export of time-averaged stress and volume fraction data for moving bodies to support detailed analysis of their fluid–structure interactions.

  • Bubbles/Particles: Output bubbles/particles controls how particle and bubble data are written, including output down-selection, exit tracking, and customized write intervals for efficient, targeted post-processing.

  • Restart Files: Output restart files controls the creation of binary checkpoint files used to restart simulations, including their timing, conditional output, and retention, balancing disk usage with recovery capability.
