Hi
Does anyone know how it is possible to run several analyses in cfd using Parameter set available in ansys workbench?
I know i can set some dimensional parameters in my model and also in mesh program but i don’t know how to define results as an output parameter

[evcelica]

In CFD post, you can make an expression for an output parameter, example max(Temperature)@plane1 then right click the expression and click "set as workbench output parameter"

You may be able to do this in CFX Pre as well, but I've never tried, I like to check the first round of results first.

tanks for the clue
i have tried what you said .i found the output parameters but there is still a problem a.while iset some design points and push the update all design points ,Ansys begins solving all the design points and the lightening sign disappears from design point's parameters one by one but no value is shown for output parameters at last. Where is the problem?

Best regards

You need to wait till the solution is stopped, it's only then the results are fetched from CFD-Post. Try clicking on the parameter tab below Results, you will see your updated results.

one more fact: afaik if you add ANY additional output to your already solved cfd-post container it will still solve again instead of just reading the res-file again.

Does anybody know, if I can use a Parameter set on inportat solid with in the ansys design modeler.. For example I can use the Extent Type on a extrusion which I have created with the design modeler but I can´t find a way to so with my imported solid.. any help would be very much appreciated!:9

I have found that there is a way to set parameters on solidwork part files imported in DModeler. just Google it .you will find some tips.

[mvoss]

activate the parameter import in the wb2.0-schematic and set the correct key (e.g. DS_...) for the wb to recognize your parameters with this key from imported CADdata and set them as parameters in DM.

[hmasenger]

have you ever imported catia part files into WB? do you know what is the catia part files correct key?

[mvoss]

Never used Catia but proE and sw. You can set the Key to whatever you like from the wb-schematic. Just Right-Click for the Options menu.

[granbycools]

if the keys don´t show up, does that mean that the catia-wb interface wasn´t installed to begin with? and we are talking about linking the cad model with wb and no igs import, right?

[mvoss]

please have a look here

yup. that's what we are talking about.we want to know if there is a way to define solidwork or catia part's dimensions as a parameters in workbench or not.

[mvoss]

please have a look at the link above. Define the parameter names in SW/CATIA with the key u like and set that key in the wb-schematic.

hi guys
I want to simulate flow over my wing for various angle of attack at different velocity. people suggested i have to look for parameters study in work bench. my case is i want to input various velocities for particular angle of attack. when I searched there are ways to change parameters in design modeler. i dont want to change my mesh. is there a way to change input velocity from workbench parameters study. can u send any tutorials for that?

[ghorrocks]

You can set parameters in CFX-Pre as well. Have a look at the workbench tutorial examples on parametric modelling for tips on how to set this up. They are available on the ANSYS community webpage.

[crusen mind]

found it.thanks a lot.

[crusen mind]

Any help on stability and control derivatives estimation glenn.

[ghorrocks]

The derivative against AOA is simply got from a sweep of AOA. If you want the time dependant ones then you need to do transient simulations where you model the appropriate motion and get the lift/drag from that.

[crusen mind]

I am getting a error in parametric simulation.

"update of solution component in CFX for design point failed. A conflict exists between the execution control in this component and the upstream component.this can be resolved by right clicking on solution cell and choosing an option from edit run defintion menu".
