If you are using CFX-5.6 you have to use a workaround. In CFX-5.7 you can create different domains with different fluid and different models too!
In CFX-5.6, define a multi-component mixture of the two fluid u want to define. Use this multi-component fluid for both the domains. Only things u need to take care is boundary and initial conidition. Use a step or subdomain function to make sure that particluar domain contains only that fluid. IN the boundary conditions (mainly inlet) make sure u specify the mass fraction of 1 for the appropriate fluid. Let me know if u need further assistance. |

In Cfx 4.4 I think I must define a multicomponent mixture.
The problem is that in the two different domain I have two different mixture. So can I set my multicomponent mixture and "separate" the fluid. But I need have two different group of properties (viscosity, Cp...) for the two background fluid. I must set this properties by user fortran? Thanks Andrea |
