Transient CFD Analysis of Rotor and Stator | Time Transformation | Ansys CFX

Hi there,
I'm trying to do a simulation of {impeller + diffuser} .

1. The following image shows the Boundary conditions of the simulation:  

 

2. The following image shows the basisc setting of Transient blade row model of the simulation:

but while processing the simulation it shows an error, as shown in Picture:

Your efforts will be warmly appreciated.❤️

Hi, there are some requirements regarding pitch ratio and number of stages to be modeled when using Time Transformation method. More details in the appropriate section of CFX-Solver Modeling Guide.

In case these are already satisfied in your setup, have you tried initializing the case with a well converged steady state solution?
