why is the defineRho in VelocityBM empty?

[Leaf]

hey, guys,rnI got a problem in openLB code, my openLB version is olb-0.8r0. When I traced the code process of Cavity2D, I found that the defineRho function used in setBoundaryValues is empty. Won’t it cause any problem? Looking for your Help. Thank you so much.rnrnrnHere is the function code, which locates in momentaOnBoundaries.hh file.rnrn

Code:

template<typename T, template<typename U> class Lattice,rn int direction, int orientation>rnvoid VelocityBM<T,Lattice,direction,orientation>::defineRho (rn Cell<T,Lattice>& cell, T rho_ )rn{ }

Hi openlb12,rnrn For velocity boundary cells the density is to be interpolated and therefore rho is not to be set. So the code is correct.rnrnMathias
