I'm working on simulation of air suction through pipes. I encounter some problems with the results of the simulation. Indeed, after setting a 20 m/s speed as a boundary condition on the outlet face of the pipe, the "probe" tool indicates speeds over 20 m/s up to 30 m/s inside the tube, which is impossible in my case. (I am looking for having 20 m/s only at the outlet, so lower speeds inside the tube.)
Does somebody has ever observed this type of error during calculation and eventually knows how to solve it ?
Thank you in advance !
