In a compressor or turbine, accurately capturing the transient interaction between rotating and stationary blades is complicated by the different blade count (or pitch) between different stage rows. This pitch change often means that a time-accurate simulation requires modeling the full wheel, a full 360 degrees of geometry —a transient simulation that is sometimes computationally prohibitive. Users can dramatically reduce computation requirements, in terms of time and memory, with the new advanced transient blade row (TBR) methods
