This is normally done by : CREF 2 1 2 CSET The command is done successfully except near the centre of my cylinder where prostar divide some cells in Theta direction. If you already encounter this problem can you help? Star-CD version 3.10

Check the help on CREFINE and you will find that for prisms, ndivi=ndivj = an even number.
