Conditional disable of nodes in model tree depending on study.

I have a model containing two studies (Eigenfrrequency and time dependant structural). I use the modal analysis to look at the resonance and then the structural to look at the peak stress with a deflection I specify. When swapping between the two studies, I keep have to enable and disable nodes. For example, I used a prescribed displacement in the structural analysis but holding the object with a prescribed displacement in the modal analysis will produce invalid results. Also, I add a little damping in the structural analysis to help out the solver, but don’t want the damping in the modal analysis.
I would find it very useful to be able to make nodes in the model tree conditional on which study is being run. Is that functionality available ?
Thanks.

Hi Dan,
This seems like a case where selecting the Modify model configuration for study step check box would be useful (in the Settings window for the Eigenfrequency study step, for example). You then get a copy of the physics part of the model tree, where you can right-click nodes to disable them for that study step (see the attached screenshot for an example, where a Fixed Constraint has been disabled for the eigenfrequency study).
Best regards,

Perfect. Thanks Magnus.
