Variable Boundary Conditions for Generating Pump Curve

BigPapi34 · March 27, 2012, 05:29

Hi,

I'm currently modelling a centrifugal pump and generating a head-flow performance curve. I am currently running a simulation for each flow (my outlet b/c is set to mass flow rate).

I am aware of how to set up configurations in order to run a frozen rotor/steady state analysis which then automatically runs a transient simulation using the results from the initial frozen rotor run.

Is there a way to do something similar in terms of generating a curve? i.e. can you run a simulation at say 100 l/s until it converges then get CFX to automatically run the same simulation again at 125 l/s, 150 l/s and so on?

Any info would be great.

Dave

Yes, you can do this either by a batch file with cfx5solve or using workbench to drive a parameter sweep.

Thanks for the info, I have now found an ANSYS presentation based on parametric studies which looks ideal.

Cheers
