Hi Dudes,

I have an 2d rectangular model, in which i have splitted it into 3 regions, I have to mesh the three regions separately with different mesh size. So whether i have to use interface in between these regions. Pls give me ur suggestions.

With regards. Abi

yeah u hv to use interface.coz the common edge in the 3 regions will hv the same interval size which will prevent u from using different interval sizes.

Hi rishikesh,

Pls can u explain me in detail, because i am not getting ur answer. Thanks for ur reply.

With regards, Abi

abi jus try meshing ur geometry without using interfaces.

u will understand what i told u.

Rishikesh

Thanks again rishikesh, then in what case we have to use interface can u tell me pls......

Regards, abi.

interface is used when u want different interval sizes in the same geometry and an edge or face is common to 1 or more parts that u r meshing.

if u hv any further doubt,feel free to contact me.

Hey rishikesh thanks a lot for ur quick reply, co operation and co ordination. Since I am using different mesh size in that three regions, so why can't I use that.

With regards, Abi

u cannot give different interval sizes to the same face/edge.

at least my experience tells me this.

i am also not vastly experienced in cfd,but whatever of gambit i hv used i think this is the case.

Ok thanks for spending some time for me, let me know if i have some problem.
