Hello sir. why do we define the output pressure as 0 pa as a boundary condition, but at the end of the analysis, when we look at the pressure at the output, we see a negative value instead of 0. It is called backflow, but I do not understand why the ratio is not 0. After all, we defined 0 at the beginning, shouldn't it not change? by the way, I am using COMSOL.

Sir, could you please do the simulation on packed bed adsorption column for the removal of heavy metal ions from wastewater.
Yes, soon
