i fixed it by extrude the inlet plane to make sure that the inlet velocity profile is parabolic.
but no progress in giving parabolic profile to the software.
hello everyone
is anybody here using comsol multiphysics?
i'm trying to model a tube which the inlet is a fully developed fluid
but the problem is how to enter a parabolic inlet profile for velocity
in 2d axisymmetric it is very simple. but my model is 3d
i've entered "r" as a variable in...
