Hello ,

i am a biginner of comsol and i am doing 2d modeling to simulate tiny tube with 0.6mm diameter , moreover, three holes size 50micronmeters in series, when the inlet was set as velocity m/s and transmit the velocity into flow rate m^3/s as the same amount, the outlet shows quite huge differnet value when sloved. Does anyone can help me to clarify what happend here.

PS, i am just start to using comsol and i am confused by weak function in comsol and how to set up the boundary condition as well.

Thank you,

have a good day , guys

Eric
