structured mesh in stirred tank
 

hi friends,
i have created a stirred tank geometry in design modeler and meshed it in ansys mesh. i have used the default settings in the Ansys-mesh except for changing the relevance from 0 to 10 for better accuracy. what i am getting is that some part are having structured mesh while rest unstructured
although i am getting result with unstructured also but i want my whole geometry to have structured mesh.

Have you resolved your problem? Because I have the same problem now. I have to do a structured mesh for the water from a stirred tank and I don't know how to do it. Could you give me some ideas? Thank you very much!
