Microchannel flow with heat transfer

Hi,

I'm trying to model flow in microchannels with a heat source.
We do have the microfluidics module, heat transfer and fluid flow but we do not have the CFD module.
That's why I do not have an access to conjugate heat transfer and isothermal flow models.
Do you think the modelling can still be done with what I have in hand?

Thanks a lot in advance.
