 December 1, 2006, 07:19 Temperature regions #1 Zoran Karabaic Guest   Posts: n/a Hello, I'm new to CFX, and need to obtain results in it, to make comparison with FLUENT. Is there some way to set temperature regions on z-axis and patch them something like petching regions in fluent. I need to obtain temperature diferents of sea layers - thermocline thanke you in advance Zoran

 December 1, 2006, 10:30 Re: Temperature regions #2 opaque Guest   Posts: n/a Dear Zoran, The idea of patching as in FLUENT is not available in CFX.. However, CFX provides you with a different set of tools to do the same thing. Do you want to set a temperature profile/distribution within a 3d or 2d region? In most cases the use of CEL expressions (mostly using the step function) is enough to set/initialize a variable on a region.. Please see for examples of using CEL.. They have been discussed in this Forum as well several times. Opaque.

Ther would be 5-8 zones over the hight of some 50 units and domain is bay 50 metars deep in one end and 5 metars the other, 3 km long, 900 m wide at widest side and 30 m at other side. I need to set initial domain with thermocline, becouse i'm modeling inlet of hot water on the side of the bay and on -45 m inlet of cold water. Need to see mixing of cold and hot water at inlet. I'm using bouyancy flow. Zoran

 December 1, 2006, 14:08 Re: Temperature regions #4 opaque Guest   Posts: n/a Dear Zoran, Write an CEL expression of the temperature variation as a function of height (perhaps Z direction) and then use it in the Initialisation panel for all domains (I imagine you associated a zone to a domain).. Select Automatic with Value and use your expression on the RHS for Temperature.. Opaque
