Finite Volumes method. Distinction between integrate and pointwise quantities. Spacial accuracy depend on ability to evaluate accurately fluxes, starting from integrated quantities. Accurate evaluation of fluxes through interface of each control volume (CV). OK inside the domain, but chalenging in case of boundary conditions : by definition non uniformity of the stencil. BC on faces instead of nodes. Enforcement of the BC by modifying the normal component of the wall gradient in order to evaluate accurate diffusif flux. Treatment of inlet BC by integrating convective flux through each boundary-facelet.
