Hi,
I'm modelling a problem with two different fluids which are not in contact.
Whenever I change the material for one of the fluid Domains, the other Domain is automatically set to the new material.
I can not have two different materials for two different fluid domains.
What's the solution for this?
Thanks

Dear all,
I think I found the solution. I checked CFX help and the only part noticing this issue was:

" Multiple Fluid Domains
When consistent physics has been enforced, all settings are copied across all fluid domains when any fluid domain
is edited with the following exceptions:...
"

To add the option of multiple fluid domains with different materials you have got to do so:
Go to Edit>Options>CFX-Pre>General
In the Physics section check "Enable beta features".
Doing so another option appears "Constant Domain Physics"
This way you can make the "consistent physics" optional.

After enabling beta features, one could disable "costant doamin physics"..
I checked in V13, it works well..
Thanks folks..
