Please someone tell me how can I mesh in ICEM 10 airfoil surface taking into account its curvature? Just like in CFX-Mesh: Face spacing type -> Angular resolution of Relative error. I need good resolution on leading edge. I use blocking to build regular mesh.

Maybe somebody knows good ICEM forum?

What type of mesh are you talking about? Tet or Hex?

Tet mesh generator is pretty automatic while hex mesh generator is semi-automatic.

If you're new to ICEM, I'll advise you to start with tutorial first. You should be able to grasp some usefull idea from there. Good luck.

In my case it is hexa meshing around airfoil. I've created block, associated its vertices to points, edges to curves. Now I need to set up surface/edge sizes. It is not a problem to set constant size around airfoil surface, but how can I set different size regarding to curvature of airfoil? I know, that it is easy in tetra mesher, but what about hexa?

In Hexa you use edge parameters to specify node counts and distributions on edges. (For default you can set maximum size on surfaces - then use edge parameters to fine tune.)

I don't quite understand your question....Anyway, you can use multi-block strategy if you wish to specify different element size (parallel edges should have the same no. of nodes)....ie. divide it into several smaller blocks.

Yes, I use this option for setting node counts (Mesh -> Set Curve Mesh Size -> Curve Mesh Parameters (for setting node count) and Mesh -> Set Curve Mesh Size -> Advanced Bunching (as far as I understand for distribution on edges). When I set Curvature as bunching law I need to specify ratios and spacings. What should I set in these options to account for curvature?
