Hello sheaker, thank you very much again for...

Hello sheaker,

thank you very much again for looking deeper into this! This is highly appreciated!

The mesh non-orthogonality max of 64 is quite the best I managed to achieve with different...

divScheme upwind

Furthermore I tried a simulation with the most diffusive divScheme I could think of, upwind. However, again bounding k explodes at some point and time stepping decreases. I guess the simulation will...

Another try

Just tried another option, and extruded the mesh at the inlet for 50 cells (2mm). The first test run again showed the undesired behaviour quite much straightaway...

I will give this possibility...

Hello alltogether,

I am currently running a simulation with a custom transient solver (based on pisoFoam, version OF2.2.2) on a grid created with cfMesh (v1.1.1, blood vessel geometry with one...
