void Nektar::CFSBndCond::v_ApplyBwdWeight ( )

protectedvirtual

@ brief Newly added bc should specify this virtual function if the Bwd/value in m_bndCondExpansions is the target value like Direchlet bc weight should be 1.0. if some average Fwd and Bwd/value in m_bndCondExpansions is the target value like WallViscousBC weight should be 0.5.
