can set 2flow type(larminar&turbulence) in 1model
 
my model is flow meter but velocity is very low. I know flow before passed blade is larminar and flow passed blade is turbulence. How to set property of flow. I tryed to run with turbulence but large error. Thanks

you should do this using the transition model in STAR-CCM+. STAR-CCM+ can also do MRF and sliding mesh.

Thank you, but I can done sliding mesh. I would like to know Star CD can set 1 Mat. and 2 flow types in 1 analysis.Ex: flow in long pipe, velocity is very low (assum larminar) pass object(can make turbulence). Can I set some cell solved with larminar flow and another with turbulence flow? Thanks

I think what he is trying to get at is that STAR-CCM+ would be a better option for you analysis, instead of STAR-CD.

Thanks Jim. Star CD v3.26 can't set analysis some cell be larminar and another be turbulance, is it?

It is possible using the subroutines. Just ask the support or search the web or try yourself. It was somewhere described how to do it. Maybe on www.adapco-online.com
