cyclone geometry help
 

hi i am very new to CFD and working with fluent on cyclone. i made cycone geometry in gambit and now having problem in messhing it.i made geometry with top to bottom approach that is by volumes and i did subtraction boolean operation to creat vortex finder. now maybe my approach is wrong and should i apply bottom to top appraoch because i can not mesh it i tried different combination for messhing. second i want to know that if i mesh all the faces then will it work or i have to mesh volume for applying model. any suggestion please and if anybody can provide me with some tutorial on cyclon or any example i will apreciate. my email address is anjumnaveed76@yahoo.com thanks Anjum

hey boy you wonna do some trial and error then check your mesh quality before exporting it.

start meshing the small volumes and proceed to the larger volumes. the danger here is that at times gambit ignore your parameters and set its own based on the earlier mesh size. if cooper doesn't try tet. Read the gambit tutorials and manual too.

all the best!!

hi by saying the mesh small volume and then go to bigger one does it mean that i can devide a big volume in smaller ones or i have to creat a geometry with smaller volumes as i told i did different boolean operations with different volumes and at the end i have only one big volume. can u suggest any good approach.
