yes enable the dynamic mesh, else you cannot access to dynamic mesh zone.
But don't change anything, since your mesh will not be updated (no layering, no smoothing and no remeshing)

hi max i have problem again..
i have two interface in my geometry in fluent i tried to connect them using coupled but the contour of velocity was so weird check this out


that is contour for initial solution..the wall is not rotating..but whay the fluid didnt pass the valve??

yes you have problem at interfaces
Check if they are well defined.
I am in vacation untill January the 4th.

but why??i think it had been defined well.. i have two surface not connected, i give that surface interface rotor and stator after that i use FLUENT to defined the interface type as coupled...

no you need to define the edges as interface.
Between rotor and stator, only edges are common

no you mean one interface for the stator edges, and another interface for the rotor edges.
In Fluent select both interfaces to define the grid interfaces

hi max..me again hope you not bored with me
i'm facing a problem..yes again...
in my dynamic analysis using moving mesh, i'm facing the negative cell problem.. can you analysis what was wrong in my simulation, why did this comes up, here is what error like to be

something is wrong since you are not suppose to change your mesh.
Check where are the negative cells

Hi my friend, I am currently working on a similar project. I have to design a check valve. Is that working for you? Shall I follow the steps of your discussion??
