gravity in fluent!
 
i want to simulate a upwrad flow of water in a circular pipe with gravity, the property of water is defined by UDF. when i set the property as constant it gets to convergence, but once i use my UDF, it divergenes. there is nothing wrong with my UDF! i try diffirent dicretion methods for pressure, eg. second orderĄ˘body force weighted and so on. Can anybody give me help!
