Hello everybody,

This is the first time I write in CFD_Online.
I am a PhD student working on tidal energy.

I would like to ask experts using ICEM which is the best strategy to build a structured mesh of a 3D water channel (rectangular cross section) with a tidal turbine (horizontal axis_hub+blade) placed in the middle.

So far I meshed a 120 deg portion of the inner cylinder domain (turbine).

My first question is:

Which is the best way to join this domain with the rest of the water channel?
-Copy and rotate the blocking ?
- Copy rotate and merge the 120deg mesh portion of the turbine?

second question:

Do I need a complete (360 deg) blocking of the turbine to join the inner domain of the water channel?(Supposing I use a create sub-topo under topology and blocking the water channel geometry separately)

Hope you can help me!

Thanks
