Hey

One easy way to extract the flow volume for this geometry using SimScale is by running an enclosure operation, as seen in this [video](https://www.youtube.com/watch?v=8N6WPR4qxvI&feature=youtu.be&t=186).

There’s no rule set in stone for element sizing. Generally you want the local surface cells to be small enough to capture the details. Setting a limit to the local cell size assures that you will have a minimum resolution.  
Also, keep in mind that the local element size of the surface is related to the inflate boundary layer refinement:

In order for you to choose good settings for your inflate boundary layer refinement, you have to conduct a [y+ evaluation](https://www.simscale.com/forum/t/what-is-y-yplus/82394)
