2nd order discreization with dbnsFoam

jensi_t · October 17, 2014, 11:40

Hello,

can anybody tell me how i can run the dbns-solvers with second order accuracy in space? I use roe flux but its said in the header file that its just first order. I don't understand how to handle it, because the flux-schemes are not defined in fvSchemes.

Thanks. Wish you a nice week-end.

Jens

As far as I understood dbnsFoam is using second order discretisation unless the firstOrderLimiter is choosen.
