[Hedge] boundary condition

[Islam El Salawi]

Hallo,

watching wing.py script, I found:

fvi2fm = mesh.face_vertex_indices_to_face_marker

in make_wingmesh(). "fvi2fm" is a variable of type "dict" in which frozensets of vertex indices are assigned to a specific integer. This integer represents a boundary condition. In this dictionary "fvi2fm" stands the following example: 

frozenset([2475, 3445, 1406]): 1000

with the specified frozenset of vertex indices and the allocated integer. My question is, why are there three vertex indices? Is it possible to create a dict with frozensets of all "noslip" vertex indices and allocate the boundary condition to it, like

wall=[0,1,4,5......2348,5990]
inflow=[35,46,57,....,134]
dict({frozenset(wall):1000,frozenset(inflow):2})

"wall" is a list with all nodes or vertices of an area with special interest. inflow is self-explanatory.

Thanks
Islam
