I am load an OpenFOAM results I downloaded from SimScale

I am wondering if there is a convention (naming or otherwise) where we can hide the simulation bound mesh and see only the inside mesh (blue in the example) ?

I am using Paraview 5.9.1 on Linux

The blue part of your dataset looks like a whole in your volume, is that correct ?

You may want to load only the region you are interested in.
