May 25, 2018 at 7:01 amhrebohmSubscriberI found streamlines crossing walls and particles following this streamlines crossing the obstacle too. I assume the underlying grid is to coarse in relation to the size of the obstacle. That means the user must get an Information of grid size to use the code correctly. Please give me a hint how to avoid this situation.

You may try running it again with maximum fidelity to get a more accurate result. Also, I would suggest you refer to Discovery Live: "Thin" geometric features and relative GPU adjustments for a better idea of how to work thin geometries.

Thanks for the answer, but an information of grid size would be helpfull to avoid problems with thin geometries, because "thin" is defined in relation to grid size.

hrebohm The information on grid size is currently not available. It is important to note that because Discovery Live is designed to provide an interactive workflow for a wide range of supported graphics cards, it adjusts the available fidelity range (minimum and maximum) to keep a fine balance between performance and level of detail. This means that depending on the available graphics memory and computational resources, the limit on what Discovery Live is able to resolve geometrically changes.

Since the grid is so dependent on hardware a graphical representation of the grid size relative to fidelity settings for given hardware would be very useful to the user to in order to identify which features will be captured.
