Hi all,

I'm quite new to Open Foam and CFD in general.
I'm working on some simulations with blunt bodies in water.

For this I've been editing the simpleFoam motorBike case. Only things I've changed are the shape of the body and the transport properties (nu) to 1e-6

I'm simulating are quite simple geometric shapes as squares with a rounded edge (size in the order of a meter) in a water current of 1 to 2 m/s

My questions is: are the standard values used in the motorBike tutorial suited for this kind of simulation or do (for instance) the values for k and omega need a change for the simulations to make any sense?

used:
turbulentKE 0.24;
turbulentOmega 1.78;

Thanks,
