    HFSS VBS Scripting problem/HFSS Registry problem

    I'm having difficulty getting HFSSv15.0 to script in Windows 8. I generate a test script by recording a script from Tools>Record Script to File. I then try to run that script again through HFSS Tools>Run Script and it gives me the error: If I instead run the .vbs file through Windows Based...

    Power coupled to higher order modes in mode converter

    Maybe I'm missing an aspect of your question but can't you simply look at the S-parameters in your simulation? To look at those you simply right click your results -> Create Modal Solution Data Report -> Rectangular Plot -> S-parameters and then look at S("secondport",3,"firstport",1) (assuming...

    HFSS overlapping objects

    I'm going to guess that would affect your simulations because the geometry is, instead of a solid conductor, a conductive surface with a dielectric inside of it. You can certainty test this simply by running the simulation with the subtracted dielectric and without the subtracted dielectric...

    HFSS: Unphysical results when simulating waveguides

    I think I figured out the issue. When I was defining my ports I stuck to the default options and was unaware that the integration line does not align the modes. Just to illustrate this in case someone else ever comes across this problem I've attached some images below. The first two images are...

    HFSS: Unphysical results when simulating waveguides

    I've reran the simulation with refined surface approx. mesh, max delta S = 0.01 and a minimum converged passes of 3. Unfortunately the results look about the same. Just some stats about the solutions: 2.0mm taper: 5 passes with 19346 tetrahedra and max delta S of 0.00093 2.05mm taper: 4 passes...

    HFSS: Unphysical results when simulating waveguides

    For the 2mm taper: 2 out of 6 passes with max mag. delta S = 0.00656 and total tetrahedra = 5493 For the 2.1mm taper: 2 out of 6 passes with max mag. delta S = 0.0179 and total tetrahedra = 5990 For the 2.05mm taper with lambda = 0.33 3 out of 6 passes with max mag. delta S = 0.0040 and...

    HFSS: Unphysical results when simulating waveguides

    The simulation produces similar results when we make a slight change in geometry but when we pick a value in between we get vastly different results. It's hard for me to believe that the physics is actually that sensitive to the initial conditions so I'm skeptical of the simulated results. Here...

    HFSS: Unphysical results when simulating waveguides

    I've only recently started using HFSS and I've noticed that sometimes I get strange, unphysical fields and solutions. For example I'm simulating a transition of the TE11 mode in a circular waveguide into a TE10 mode in a rectangular waveguide. Below are two animations of this transition. The...
