A multi-region mesh was assigned - this analysis-type requires a single-region mesh.
This is my problem with my project.
You can see with this link

I did surface refinemen,but still the same problem?
If any suggestion can help with this problem?

Please have a look at this thread and subthread linked in it: CFD multi-region mesh error

Best,

Basically you have 2 regions (walls of the pipe + flow region). An incompressible analysis requires a single region (namely the flow region).

To solve this issue, simply toggle “Keep existing parts” off, re-mesh and run the simulation.

If i do that i will face another problem with meshing!!!
I did that already.
