 February 2, 2005, 04:00 UDF_Cell variables! #1 ROOZBEH Guest   Posts: n/a Sponsored Links Hi; I want to find a face (or edge in 2D) with maximum length in a cell (largest face of a cell). I want to calculate this value for all cells. How can I do this? I want to use a formulation includs maximume length of edge in each cell. Thanks
