Fluent does not use staggered grid. Please have a look at the user guide. Luca

Hi Luca Thank you for your advice. I need to evaluate pressure gradient. This should be nondimensionalized so in difference form that is pressure difference of cell and face centers divided by their distance. But without staggered grid I can not do it. Have a nice time. Mech

Fluent enables you some UDF functions to give you directly pressure gradient. have a look ad Fluent UDF guide. Luca
