two boadies with same boundry

In STAR CCM+, is it possible to draw two bodies which has a output and the same time that output is a input to the other body

Yes, just create an in-place interface.

Thank you very much LuckyTran,Yes i have done it now and now another error comes and it says zero mass fractions in those areas (as im modelling gasification and i was trying to model it by separately defining pyrolysis ,combustion and reduction zones.).i have created the interfaces in the two boundaries which divide pyrolysis zone feom combustion zone and second one combustion zone from reduction zone.do you have any idea about it.
thank you

It seems you are using a different physics continua for the two domains, right? In this case you cannot handle their connection with an interface. Instead you can use either a table to extract data from the outlet with Auto-Extract option every iteration. Then use the same table as inlet data for the inlet in the other region. Please note that this approach is not conservative.
An alternative approach is to use a surface data mapper to map the data every iteration from the outlet to the inlet. Use the Mapped Field Functions as inlet data.
