icem hexa mesh parts pb
Hello dear colleagues,
I’m simulating a flow over a symmetrical NACA airfoil using,to have a multiblock structured mesh, I have done a 2d extruded mesh using ICEM HEXA(v11).the steps followed are:

1-generating 2d geometry (airfoil+rectangular domain) using a scripts file. creating parts representing geometry families.
2-2d blocking (several operations) and 2d mesh.
3-extruding (1 layer) the 2d mesh after converting to unstructured mesh.

Results: having a 2d extruded mesh. But parts still representing lines and not sides. making pb to introduce boundary conditions (inlet,outlet,wall and airfoil).

please, I will be grateful to receive any idea or suggestions.

If i were u, i shall use a 3D geometry, using another cad software.

thanks,for your contribution Rogerio.

did you set the inherited option for the new sideparts?

i have done this,but...
Thanks a lot neewbie,i have done this,and it helped well.
but there is a pb whith some lines and shells that need not to be(on profile part,and top part).

pb??!! didnīt get it.
only associate the faces/surfaces ...which means in the part selection you only pick the shell part.then there will be no extruded nodes/lines- but that would lead to the same names for the top and side part...hmmm.
did you set up the all parts you need before you do the blocking-->to unstructured mesh-operation?
