Thanks again.

I figured out that in terms of temperature, for a constant heat flux case, there is an analogy with pressure i.e. there is a constant jump in the flow for subsequent repeatable...

Thanks for your answer! It really helps.

Yes, I found convergence is much better with meanVelocityForce than using a jump in pressure. As you point out, I also need to control the flow rate...

I made some progress with this case.

I have the periodicity in all three directions, and the case run without problems.

I used cyclicAMI in all the directions, and add the following to...

Thank you for your answers.

I thought I would go about this step by step:
- first, will try to set up cyclicAMI in the 2 directions perpendicular to the flow.
- second, I will try to implement...
