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.
