Different models in a single domain

I'm trying solve my problem using FLUENT. I want to split up the whole computational domain in to two or more blocks. I need to use different solution models in each blocks. And I need a developed flow through the domain. How can I solve this problem? Can anybody help me?

Or, If I solve each blocks individually, then how can I input the output data from one block to another block calculation. Is their any technique or UDF to solve it? Can anybody please help me?

Thanks and with best regards

Re: Different models in a single domain

I have similar problem. I am calculating gas and liquid and I have to use 2 different turbulent models for each phase. And ... I do not know how to do this trick :)

Re: Different models in a single domain
If you decide to solve each block individually, than it is actually easy. First you calculate your first block, than you can just use this command:

File-write profile - (velocity, temperature what ever)

and this profile will be input for your second block using similar command

File - read profile...
