Outputs by Analysis Type

This document lists all the possible result outputs in terms of physical quantities/variables per analysis type after a simulation is performed in SimScale.

Fluid Dynamics

The solver is OpenFOAM based and therefore results are exported as an OpenFOAM case file that can be downloaded and stored locally, and post-processed in 3rd party applications such as the open-source ParaView post-processor.

To learn more about the result control feature for fluid flow analysis in SimScale please refer to this page.

Data Plots

Data plots are displayed as 2D plots on the platform with the field against time in the x. The plots can be downloaded in many types of images, but importantly, they can be downloaded as CSV files for further processing.

  • Area averages and Area Integrals: All default fields.
  • Probe points: All default fields.
  • Forces and moments: Pressure, viscous and porous forces and moments on a selection of faces.
  • Forces and moment coefficients: Lift, drag, and moment coefficients on a selection of faces.
