Hi everyone, I have a problem regarding overset mesh. This is my first attempt at using the tool motion and also trying to do overset mesh. I am not sure why the region containing the savonius wind turbine does not blend in together with the rest of the body.
The process of me creating this model is as below:
a vertical axis wind turbine model
a cylinder covering the wind turbine
a block
subtract wind turbine from the cylinder [1]
subtract the cylinder from the block [2]

assign [1] and [2] to region

This image is the pressure scalar scene.

Any help will be appreciated. Thanks in advance.

Why subtract a cylinder?
