Parabolic profile.
Hello,
I am new to open foam,i made a geometry for a rectangular duct in Blockmesh dict.With all fixed walls.I need parabolic velocity profile for my rectangular duct.Can any one help me with this Attached are the files for P and U.Here i am using laminar icoFoam solver. http://imageshack.us/a/img266/684/7y6y.jpghttp://imageshack.us/a/img191/6936/x2wl.jpg |
i understood that you want such profile as input for solver. you have three options.
1-using groovy BC. 2- using polynomial BC (i am not about it ). 3- using another software to give you values of velocity at each height for your profile,but number of points must be equal for number of cells in y direction in your mesh. also number of cells in z direction must be one. then use nonuniform instead of uniform in velocity bc at your inlet. ex: inlet type fixedValue; value nonuniform number of cells ( values each on in single line ); |
parabolic profile
I thank you for the reply,
But you mentioned other software,do you mean ansys fluent ? |
Groovy bc
But i am not sure how to implement groovy bc for laminar solver(Icofoam),could you please guide me through this ?
