I am trying to figure out how to set a cylindrical domain in Phoenics. I will simulate concentration distribution in a circular tank. I really appreciate if you would like to give me some suggestions.

you can set "cartes=F"

Thank you so much for your reply. Phoenics has Cylindrical-polar coordinate system. However, what I need is a cylindrical system. My domain is a cylindrical tank. I will appreciate is you would like to help me to figure out this problem.

The answer you were given is correct. Set cartes=F - that will give you a pie-wedge part of a cylinder. Then you must set the size of the radial direction (which I believe is called the "x-coordinate" in PHOENICS) to 2*3.14159... - that is, two times pi radians - in order to obtain a complete cylinder.

Dear

Thank you for every think, I am "Mohammed Alzuhairy" Iraqi engineer and Ph. D student in Chemical Eng. Depart.,and lecturer in Chemical Eng. Depart., University of Technology(Baghdad-Iraq), I read your Message in site(http://www.cfd-online.com/Forum/phoenics.cgi). Dear My research focuses on the implementation and validation of computational fluid dynamics (CFD) tools for Heat transfer in bubble column(gas-liquid-without reaction)., therefore I need CFD Software to setup in my computer(laptop) because it will help me so much to complete my PhD research as "heat transfer in bubble column for viscous liquids"," Nonlinear analysis; Dynamic modeling" Dear you know that I am Iraqi engineer and I live in Iraq in Baghdad exactly not in Japan or USA or . . . ?, so I can't write my state and zip code in internet forms and I have no credit card, no deal with it in Iraq, then I ready to pay any sum of money, but how?. If you want to help me please send me(post it) to my address as shown below(my University) cd of CFD (package Cham (record on cd)) and I ready to send you any or all informations about me or my Ph.D research and also I ready to send you all results of my reseach as you like.

With my Best Wishes . . .
