Now we have to create the mesh,

right click continua $\rightarrow$ New $\rightarrow$ Mesh Continuum, to choose models right click on Models $\rightarrow$ Select Models

The mesh consists of predominantly non-uniform rectangular cells with fine resolution near the nacellein order to capture the boundary around the nacelle. This will allow us to optimize the computing time.

a zoom on the nacelle region shows the refined mesh in this part:


We can also make the mesh finer on a selected block, as the following figure shows:

Finally the mesh is generated by successively clicking on the the following buttons
