Post-processing via 3rd-party solution

The workflow on the SimScale platform is kept as modular and open as possible what allows you to use a third-party post-processing system to analyze the results. Find below a brief tutorial on how this is done.

How to post-process via a local ParaView

As soon as your simulation run is finished, you get notified via the Job status box or the Notification box with a Finished notification. This means, that the results are ready for post-processing. Here you can see a brief tutorial on how to use ParaView for analyzing results generated on the SimScale platform. ParaView is an open source visualization application provided by |http://www.kitware.com/| that you can download and run on many different platforms (see the link above). The steps for visualizing results of the SimScale platform in ParaView are explained below.

Download the results

As soon as the simulation run is finished, you can review the residual convergence and other properties of the run when clicking on the run itself in the Navigator tree. At the bottom of the settings panel, where you also start and stop the run, there is the button Results. Download results appears as an option in the Results button

When you click the button, the generated results are packed and ready to download in a packed archive.

Depending on the browser you are using, the archive that is downloaded should be visible. In Chrome, it is displayed in the bottom panel of the browser.

Depending on where you set your default download directory, the archive with the packed results should be there. The picture shows the standard download folder of a linux operating system.

For most of the results, the files are already ready for opening them with ParaView. In case you ran an OPENFOAM® case, you have to add file called *.foam such that ParaView can read it in. In this case, we simply add an emtpy text file called ‘case.foam’.

Add an empty file with ending '\*.foam' - in this case: 'case.foam'

Add an empty file with ending ‘*.foam’ - in this case: ‘case.foam’

Now the result folder is ready to be imported into ParaView. Therefore open ParaView and click on Open. Then choose the ‘case.foam’ that we’ve just created the step before. Based on the ending ‘*.foam’ ParaView automatically chooses the OPENFOAM® reader and reads in the result files correctly.

Open the 'case.foam' file in ParaView

Open the ‘case.foam’ file in ParaView

Now you can choose on some parameters how the import shall be done and then hit the Apply button within the Properties tab.

After clicking on Apply the data is imported

Then the data is imported and you can use ParaView for further processing of the results.
