I mean I see that even ICEM can support a bottom up approach like you create some initial blocking , then delete it but after such initiation of the block, ICEM makes it possible to build blocks from the vertices by using the option - " From Vertices/Faces " in the Create Block options also it is possible to extrude faces of a block in ICEM so how does this differ from the bottom up approach used by gridgen. __________________ Best regards, Santhosh.
