FiPy Experts,
I've run into some trouble creating a grid to extrude, and suspect I'm organizing my grid incorrectly. I'm creating a quadrilateral grid and have numbered each cell in a clockwise order: vertex numbering like this: 5-6-7-8 | | | | 1-2-3-4 cells in input file to be extruded labeled: cell vertices --- -------- 1 1,5,6,2 2 2,6,7,3 3 3,7,8,4 Is this correct? Is there a place in the manual that indicates how this should be done? I've also tried counterclockwise ordering but get negative cell volumes... Thanks, Andy ---------------------- Andrew Reeve Dept. of Earth Science University of Maine Orono, ME 04469
