Hi. Has anyone seen this issue before,
I have once but cannot remember what caused it
Thanks
Ian
I sometimes get this error when implementing a new DataGroup cell incorrectly. Check to make sure the penetration cell is in the search path for DataGroup cells defined by TFDIR_CELL or ATFDIR_CELL. It could also be an error in the catalog definition for the user defined penetration type.
