Dear Jepson,rnrn You actually fix the viscosity. Then, the Reynolds number just depends on a characteristic length and speed you define. I recommend having a look at “”example/cylinder3d”” to get an idea of how to model a similar situation. If you want, you can send me your problem set-up by email.rnrnMathiasrn
