Hello CFX users! Could anyone please give me some examples or explanation about source specifications in multiphase flow? There are no source specifications in Tutorial 15 and 16 in CFX 5.5.1. However, according to the governing equations sources are very common. I am really puzzled. Looking forward to your comments. Thanks.

Best regards David

Re: sources
If you transform one phase into another (mass source and sink will exist) for example... That is quite straighforward to implement in CFX-5 using cel and ub-domains.

Re: sources
Thanks. What does "ub-domains" and "cel" mean ? Does it mean "sub-domains"?

Regards David

Re: sources
Sorry, another question. How to generate mesh for a very long pipe with narrow diameter, for example, with 2 metres length and a 0.02 metres width?

Re: sources
A Hex mesh would be best for this pipe. You can switch the meshing mode to Patran Meshing from the Preferences menu in CFX-Build to allow Hex meshing. Your support rep should be able to tell you more about using this feature. Mike

Re: sources
Thanks Mike. First I want to try Patran method.
