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.

Analysis Types

Fluid Dynamics

Simulations carried out in the SimScale platform can be post-processed via our online integrated post-processing environment. In addition, OpenFoam and LBM Solver results can also be 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.
