    Which product are you using? Also, can you please share when you get this error message (when you launch the product or what you are running a particular model)?

    Thank you.

    I am using HFSS. I got this error when running a model. In the model, I have defined a sheet as layered impedance and has assigned the desired material on it.

    It does not look like a model-related problem.

    This may be a user-access-rights related problem. Are you running HFSS as admin/superuser, or as a restricted user? In the latter case, ask your admin to provide full access rights to the mentioned directory.

    Hello- This error can cause due to different aspects of the simulation. Sometimes a convergence issue within the model also ends up in such errors.

    Please attach an image of the profile data (Results>>SoultionData>>Profile>>Export) so that we can guide you accordingly.

    Best Regards,
