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?
