IS Phoenics good for multiphase simulation
 

I am a beginner in phoenics, I just wanted to know whether phoenics is better in multiphase gas-solid or gas-liquid case. should i go with it? if yes then how can i start learning work in it. i have worked on fluent before.

You may have to wait a while to get a good reply on this forum (PHOENICS). It's a lot less active than the fluent one.
Here are a few links to get you started:
CHAM website:

POLIS help and online information system:

Here is a very good page contained within the POLIS system on multi-phase flow simulation in PHOENICS:

Good luck!
