      Hi everyone

      I was wondering if in FLUENT 2020R2 for adopting a convective outflow boundary condition we need a UDF or it is the same as the outflow option?

      Many thanks

      Hello I'm not 100% sure about what you mean by a Convective Outflow Boundary condition. In Fluent, there is an 'Outflow' condition where the diffusion flux for all flow variables is set to 0. For more information, please check the following link in the Fluent User's guide.
