interface
 

hi every one i want to studie the flow simulations in the stirred tanks for this i use silding mesh but i can't undrestand how i can use interface between stationary and rotating blocks can any one help me thanks

Re: interface
 

create a mesh for the rotating part and completely separate mesh for the static part. Each should have a surface mesh for the sliding surface of revolution. Then tmerge together or append grid then define>grid interfaces and set moving fluid as MRF zone.

thanks for this information I used this way but the velocity of fluid is different of zero only in the rotating zone in the static part the velocity is zero and i want to know what is the difference between moving mesh and moving reference frames thnks any way
