  3. I get an error message when I run the AFSURF macro for a case which involves a serpentine passage. ANSYS tells me that the EN command cannot store an element because one or more nodes is not defined. What circumstance may cause this? I am running ANSYS 9.0.

      The macro is known to fail if the distance between the serpentine passages is spanned by only one element. The work around is to refine the 3D mesh before running the AFSURF macro. Make sure there are at least two elements between them so that each 3D element is associated with no more than one surface element.
