Hi guys,
I have to write an expression which takes in account the rotational speed of an impeller from 0 to 6000 RPM. Can someone help me? |

Francesco,
Can you send the expression? Does the speed changes with time? |

The point is that I've never write an expression before and I have no idea how to do.
It's something within step(Accumulated time step + ...). I just need a way to reach 6000RPM from 0. |

The CFX tutorials are a good place to start. Maybe you should do some simple expresions to get the hang of it. Then move to the more advanced stuff.
