no-slip boundary for flow over structured surface

Lattice Boltzmann Method LBM: Algorithms
#1

Hello everybody,

I am looking for a solution to implement no-slip boundaries for a structured surface.
http://s14.directupload.net/images/141114/ctci2dkc.png
The surface is implemented from boolean mask

[code=“cpp”]
MultiScalarField3D boolMask(nx, ny, nz);
plb_ifstream ifile(“geometry.dat”);
ifile >> boolMask;


and the only way I know to define a boundary condition is bunceback
[code="cpp"]
defineDynamics(lattice, boolMask, new BounceBack<T,DESCRIPTOR>, true);

It should be possible to define no-slip bc for every wall part by using

[code=“cpp”]
boundaryCondition->addVelocityBoundary1N(WallPart1, lattice);
setBoundaryVelocity(lattice, WallPart1, Array<T,3>(0., 0., 0.));


but defining it manually would take a lot of time.
Is it possibile to define the no-slip boundary automatically?
Or does anybody know another solution?

I am thankful for any help.

Best regards
Andi
