If you're talking about a hex mesh - Edit Blocks > Fix Inverted Blocks. Then recompute the mesh. Should do it.

Look out for double vertices. Sometimes there are two vertices at the same position. This happens if you get confused during cutting blocks. Let ICEM show you the number of the vertices, so you can see if this is the reason. If it is, merge the vertices.
