Dear all,

I'm now trying to define a inflow boundary condition using a specified discrete velocity profile when simulating with the IncNavierStokesSolver. Specially, the inflow velocity profile I use here is a Blasius profile. Since it is numerically solved by an external code, the profile here is  in discrete form (i.e. velocity on discrete points).

While from the user guide, I can see that a profile with an explicit expression can be directly implemented as a boundary condition in the .xml file, it seems that there is few examples on how to deal with a specified discrete velocity profile. I wonder if there is any way to implement this kind of boundary condition in Nektar++?

P.S.:

To solve this problem, I wonder if  the module "interppointdatatofld" of FieldConvert should be used? If so, how to  use it for the boundary?

Besides, I think here a ".bc" file which is mentioned in 3.3.5.5 Boundary conditions from file in user guide might be needed,  but I don't know how to construct this kind of files?

Thanks in advance for the help.

Best Regards,

Mona
