How to divide a surface?
 

:(Hello to everyone!
Does anybody of you know how to split/divide a surface?
To better say: I have a body with a hole inside; the surface of the body that is in contact with the hole, i want to divide it in two part...because then...when I will set the boundaries condition, i want to give to these two different part of the same surface, 2 different setting.
Is it possible?
thank you very much...I really need your help!!!!

hey,

which mesher?
For WB mesher --> draw the circle whereever you want to have it and extrude it by imprinting surfaces; you have to unfreeze the "imprintable" body before.

For ICEM --> draw the circel.... and then just cut the face by curve and add a new part for the "circlesurface"
