I was redirected from the old support portal. Posting the same question here. The original SR# is 1794782461.

Update:

• This seems to be an issue with the 18 version. The original OnDieSprialInductor UDM runs well in HFSS 15, but not in 18.

Hi 

I was trying the OnDieSpiralInductor  UDM that shipped with HFSS. I can add the model and change its parameters with no problem. However, when I try to simulate the setup, I get the following error. 

 

"

  HFSSDesign1 (DrivenModal)

    [error] Objects "ILD" and "Inductor" intersect. (2:584 PM  Aug 13, 2018)

" 

 

Obviously this is due to the ILD and Inductor intersecting each other. This seems to be a problem with UDM script. For the sake of demonstrating the simulation problem, I removed the creation of the ILD from the UDM script and saved it as a new UDM with the name "Inductor". 

 

After setting up everything correctly and passing the green "Validate" check, HFSS gives the following messages before halting the simulation.
