Hi


I am new to Fluent and am wanting to apply a Multiple Reference Frame model to my simple centrifugal pump geometry to analyse the flow behaviour within the pump. I am using an assembly of two components the first being a solid impeller and the second being the geometry of the wetted surface area within the pump housing and volute, please images below. I used SolidWorks for the generation of both components. My currect concern is how to create the multiple zones where two fluid zones are connected via an interface boundary so as to later define the rotating frame in Fluent. I am not sure how to created this in Design Modeler.


Although I am sure this step is rather simple for those already understanding how to create these multiple fluid zone boundary interfaces, It has proved rather challanging for me even after devoting a significant amout of time to understanding this step.


I appreciate any assistance in helping me understand this process.

There is no need to do it in DM. Treat both separately in DM as well in ANSYS meshing. You should create the interfaces for MRF in Fluent/CFX.
