HFSS API script fails

Hello,

This script fails on line 3. I serached for this problem and it was suggested to ad a pause between line 2 and 3. tried pause(100) and it did not help. However if I go step by step it does work.

Also if I change oProject.GetActiveDesign(); by oProject.SetActiveDesign("HFSSDesign1"); it does work but that requires the a pripori knowledge of the design name. not sure how to get that.

I contacted Ansys Tech Support, but they doe not support MATLAB API.

Any thought?

Thank you

oProject = invoke(oDesktop,'OpenProject',full_path_name);
oDesktop.SetActiveProject(oProject.GetName())
oDesign = oProject.GetActiveDesign();
oModule = oProject.GetActiveDesign();
oEditor = oDesign.SetActiveEditor('3D Modeler');
