best CFD software for turbomachinery

sam

Which software is best for simulation of turbomachinery based on following three criteria:

1. It should be capable of simulating multistage turbomachinery.

2. It should be capable of simulating the multispool turbomachinery e.g one stage of high pressure turbine and one stage of low pressure turbine on different shafts with differnt rotation speeds. further more having opposite direction of rotation.

3. It should be capable of simulating the real fluid properties including variable Cp, K and viscosity.

Any suggetion would be highly appreciated.
