blade computational domain
 

how to determine the shape and dimensions of computational domain of blades if i have blade geometry(stator and rotor) for a stage already modeled not produced in Ansys blade generator. I attached a photo of a mesh of similar blades but i don't know how to determine the dimensions of the domain and how to model it do i have to do it in design modeler and how to determine its dimensions and shape? if anybody have an idea how to do it,help will be much appreciated.
