I am trying to mesh a straight channel in ICEM. On the channel wall, there is catalyst coated on it and the leading edge of the wall is inert for numerical convenience. Namely, the wall is divided into two parts: one is inert wall and the other is catalytic wall. The picture below shows the detailed geometry and part list in ICEM:
My problem is: after I import the generated mesh into fluent, the catalytic wall and inert wall part is missing. Instead, a wall named geom emerges as the whole length of catalytic plus inert wall. The picture below shows the boundary condition list in fluent:
Can anybody give me some suggestions on how to solve this problem?
Thanks very much!
