Hi,
I am simulating lobe pump.
It is 2D, Ideal gas density, Transient, Dynamic mesh problem.
After simulation completion I observed that sufficient pressure does not built in chamber 01 after compression.
It is observed that pressure, mass, velocity & flow occures through a small gap which seperates chamber 01 to chamber 02.
In my geometry there are three such kind of small gaps for three chamber.
How can I isolates or do leak proof these chambers?
Is there any command or UDF in Fluent to do flow less region by giving coordinates (X & Y) of that rigion.

Note- The small gap is necessary for mesh consistency in Dynamic mesh problem
