How to generate good CFD meshes for very small models

The other day I was giving @hannes_seifart’s model from this project a quick spin on SimScale: SimScale . While doing so, I ran into a small hurdle during meshing, where there is actually a simple fix, that I wanted to share here (thanks @Ali_Arafat!): The model characteristics are that it’s overall very small (a few centimeters) and that it additionally contains very small, but important features. Especially these small pipe-structures, that are crucial for the flow and therefore need to be re…
