Point Inlet

Jane · March 31, 2009, 22:05

I'm doing a square box filling and i need to create a point inlet on the box surface.
the problem come when i want to create a point as a inlet for the box.
the boundary conditions set in the gambit is not allow to use point as a inlet. so what i can do....

Please help me...

hi Jane,

In my opinion, a inlet which is a point is meaningless physically 'cause the v,q and force partly depend on the value of the area A.

I suggest you give a tiny area to this inlet instead of the point.

seconded.
Fluent will calculate volumetric flowrate by multiplying c/s area of inlet with inlet-velocity. A point does't have any c/s area.

Have you tried with point injection?

nope.
I am using a small c/s as my inlet for injecting tracer element

hi satheeskannan

what does c/s area mean?

sorry
c/s - cross sectional area
