I'm relatively new to Ansys products. I'm trying to do a parameter study using Spaceclaim and Workbench.

I created a couple geometry parameters in Spaceclaim. Then I deleted them, and recreated them with the same names. I did this a few times as I was building my model. Unfortunately, it seems that the Parameter Set in Workbench seems to remember the deleted parameters. How do I refresh Workbench so it only has the parameters that are currently in Spaceclaim?

Oh no.... I tried to modify one of the parameters in Workbench, then refreshed the geometry. I received this error. Maybe it's related?

I am getting the same issues. I wish somebody could address this, it would be of immense help!

I found that if you go to the variable that you are using for the input parameter and then uncheck the "use as input parameter" checkbox, save the project, then go back and check the checkbox and it should clear up the unused parameter.
I also found that in the case where you delete an expression or variable that you used as an input parameter it will not delete it from the Workbench parameters list. To get around this, remake the variable that you deleted, i.e. if you deleted a variable, that we'll call X1, that was an input parameter, remake the variable X1 but this time don't check the "use as input parameter" checkbox, save the project, and it will be deleted from your parameter list in Workbench. Then you can go back and delete the variable again.

Does this work in 2021R2? The option of "use as input parameter", I've seen it in Fluent. The only other close option that I see in the Properties of Outline under the Parameter Set tab, is the Usage option, as seen below, and it is greyed out
And it is not part of any expression.
