Velocity cyclic BC

oscar_urri · July 25, 2012, 13:09

Hello Foamers!

i'm still kind of new to openfoam and i would really appreciate some help,

i would like to know if there is a BC that can introduce a velocity discontinuity in the solver,

i'm trying to simulate a wind turbine in simpleFoam,

i have already done it with a bodyForce and the Fan BC (pressure jump)

so my question is:

is there a BC similar to the Fan BC but instead of making a pressure jump, that it would make a velocity jump?

i'm digging deep into the codes and i think i'm getting more confused than anything else

thanks for your responses in advance

Hi Oscar,

Have you got any further with the Velocity Jump Boundary condition.

I am looking for the same for a fan circulating air in a closed Region.

If you come across something. Kindly share.

Thanks & Regards
