Hi
can anyone help me to write a complex boundary condition without swak4foam? I wanna set developed velocity boundary condition in inlet of pipe, its formula is: V=V_max*[1-(r/R)^2] openfoam has simple boundary condition type such as "fixedvalue, fixedgradient and mixed" . How can I implement a variable Bc with posotion without swak4Foam? thanks |

Hi,
You can use the codedFixedValue condition. Best regards, Fumiya

Hi,
You might want to give it a try for improving your understanding. There are some good materials on this topic: http://www.sourceflux.de/blog/the-co...dary-condition And, there is parabolicVelocity condition implemented in foam extend: https://github.com/Unofficial-Extend...abolicVelocity Hope this helps, Fumiya
