Creating a Parameter Study

Hi everyone,

i know this is probably a simple question but i just can't seem to work it out or find the information i need.

I have a model set up that works fine, though i need to run it for a large number of different velocities and i want to know how i can make this automated.

Using the Ansys workbench i changed the Input velocity to a parameter, though i don’t know how to make it solve for all of these parameters or at least provide the Fy, Fx and Fz forces for each of the runs as a output parameter.

If anyone could help me, that would me much appreciated, as it seems crazy to have to run each simulations separately when only input speed is changing.

Thanks

You can do this in workbench or you can script this in CFX only. I prefer to run with CFX only - so I would generate a series of CCL files for the input conditions and script up a series of simulations. You can get your output results with scripts too if you want, the cfx5mon command (I think that's the one) can script extraction of monitor point data and you can assemble the output from that.
