Info

SimScale can also display the mesh over a cross-section when post-processing simulation data. I’ve never run into mesh size limitations with this method so even if the Mesh Clip tool wasn’t working on a mesh, this method might. Obviously this method requires the simulation to be solved first and so it shouldn’t be used to develop the mesh initially, but could be useful later on. This is particularly useful for checking if any unexpected results are actually artifacts from mesh defects.

Beta Interface

Selecting New Beta Interface will bring you to the new interface. Maybe by the time you’re reading this, SimScale will have made this

the default interface. Either way, it’s pretty similar to the old one. The geometry viewer is mostly the same, but the panel in the upper left is different. There’s a section called Parts Color, which allows the colour and opacity of the geometry to be controlled or allows the geometry to be coloured according to a simulation variable. There’s also a button that says Add Filter. This is where you can add all the visualizations that were available in the legacy interface. After adding the filter, many of the same options from the legacy interface now will show up in a new section of the left panel. You can toggle the visibility of the filter by clicking the slider to the right of its name and you can delete a filter by clicking the garbage

icon to the right of that slider. One other big difference is that the range of a scale bar is changed by directly interacting with it. Simply click the minimum or maximum value and type in the desired value.

ParaView

After it loads, I would change the time point to be the most recent time point that was simulated as this should be the most accurate point of the simulation. Now, we can start processing the data. ParaView works by adding filters to the data file. Every filter you add will show up in the Pipeline Browser, below the .foam file. To see a list of all the filters ParaView has, go to the top menu bar, hover over Filters, and then hover over Alphabetical.
