I am trying to do a parametric study that includes a Harmonic Response analysis after a Modal analysis. When I try to alter parameters and run a deisgn point, I get the following error: "Unable to Start the Mechanical editor": 

This error only happens when the Harmonic Response block is added to the model, if I try to update a parameter and run a DP having only a Modal analysis block, everything works normally. 

I am also unable to delete the Harmonic Analysis block from workbench after this happens, when I try to delete it the following message shows:

 

However, I can delete it from inside mechanical. Also, if instead of running the design point from workbench (in the Parameters tab) I set it as current, open the editor manually and solve from there, everything works fine, the Harmonic Response is able to solve normally, so the problem seems to be in using the parameters in conjunction with the harmonic response analysis.

I am using a geometry imported from Solidworks and using Ansys 2024 R2, no problems with licenses as I can open and run the editor normally if I do it manually.  

I have tried to run the same simulation file in other machines and the same errors happen. I have tried re-installing ansys (making sure to do so as administrator), tried to change the the v242 folder to v242.old and still the same thing happens.

I also tried to create an entirely new workbench file, with a new geometry (a solid block, for testing) using the modal and the harmonic response analysis, without changing any configurations from default, and still, the same error happens, but I had previously done this kind of analysis without a problem in older versions of ansys.

Can anyone help me find what is causing this? Thank you!

I see your modal and harmonic are not  shared beyond the "model" cell . Any specific reason ?

My advise is to raise support request with Ansys technical support.
