# block.gp.bc

Syntax

v = block.gp.bc(bgpp<int>)
block.gp.bc(bgpp<int>) = v

Get/set the gridpoint boundary condition indicators (0 = free, 1 = force, 2 = viscous, 3 = velocity). By defaut get/set a vector of three components. Optionally specify a component to set/get (1 = x, 2 = y, 3 = z)

Returns: v/INT - vector of boundary condition indicators v/INT - vector of boundary condition indicators :int: - component bgpp - block gridpoint pointer
