Hello everyone
How can I run a sweep study in STAR-CCM+? I mean something like sweep studies in let's say, COMSOL multi physics where you can do a sweep on a certain parameter and the software automatically runs all the changes in that parameter and reports the results.

My case is: I wanna do a sweep study on different turbulence models on a certain geometry and second is that I wanna change the drift angles of a ship model while analising drag force and propeller wake. So the question is that how can I adjust the software to change the drift angle automatically and calculate for the reports; Something like what COMSOL does.

My guess is trying with Optimate.

Any help would be appreciated.

you should use design manager which does exactly that and is far better and is replacing optimate but i dont think you can vary turbulence models as part of such a parameter scan yet other than including a java macro in the mix

Greetings.
Tnx for the reply. Can u be more specific? Or even address some tutorials which do so?
I rather avoid using java macros as much as possible

there are two tutorials to teach you but it is very easy to use
Tutorials > Design Manager > Optimizing a Static Mixer
Tutorials > Design Manager > Design Sweep of a Static Mixer

Tnx a lot!
I think I know what to do now.

I've been through these tutorials, but I don't know if they'll fit my simulation:

Geometry: 2 Simular Cars within a tunel varying their distance
Outputs: Drag (Force), Lift (Force), Roll (Mom), Pitch (Mom), Yaw (Mom)
Variable: Distance between 2 simular bodies (cars)

Could I have some type of Outputs for a range of Distances of the 2 bodies?

very easy using either an exposed parameter in 3d-cad for that distance

or define a parameter in tools then use this to perform a part transform in a mesh operation prior to a unite or subtraction depending on how you have created your cad of each car
