I come from the Fluent world. Just trying to run your CHT gas/water heat exchanger tutorial. Conjugate Heat Transfer in U-Tube Heat Exchanger | SimScale

Now when I select the fluid (e.g., water, air) the extracted volumes (geometry) disappear. I tried in Chrom and Edge browsers.
I searched the forum. I would appreciate any tips you make have.
