Hello! I have problem concerning the mesh quality of my simulation. It consists of a small hydraulic turbine (aperture:380mm, length 500mm) which is situated in a channel (3000mmx3000mmx6000mm) and is only driven by the kinetic energy of the water. To simulate this application I have two parts the hydraulic turbine and the channel. After some time I have managed to mesh both with high quality meshs keeping the edge length ratio under 100 and the element volume ratio under 20.
However if I combine both meshes in CFX-Pre and start the simulation the values of the maximum mesh expansion factor and minimum orthogonality angle are never in the range of a good quality mesh.
Does somebody know how I can manage to get the minimum orthogonality angle and the maximum mesh expansion factor to stay in the range of a good mesh?
Thank you for your help.
