hello
my first interaction with fluent is in my final project at mechanical engineer department.
the project is about a design underwater propeller in a tube
my analyze result is not correct because of the mesh
mesh result:
skewness: 0.8475 max
ortogonalety: 0.88255 avg
aspect ratio: 1.794 avg
my question is how do i improve my mesh
i attach some photos of the mesh and mesh sizing setting
thank you all
