Hi all,


I am trying to use snappyHexMesh to generate a multi-region mesh of a heated solid cylinder inside a fluid domain. To get started, I am trying to understand the snappyMultiRegionHeater tutorial. The issue I am facing with my specific geometry seems to also be a problem in the tutorial. Specifically, the default snapControls settings in the tutorial do not result in accurate snapping. For example, if you compare the heater.stl geometry from the tutorial with the final meshed heater (using the unchanged tutorial settings), they clearly show low quality snapping. Please see the attached pictures.


I have tried changing the snapControls settings, but I cannot seem to improve the quality of the snapping. Because the tutorial case does not seem to work correctly, I'm having trouble working with my specific more complicated geometry.


Please help! Thanks
