    Using the HFSS modeler to merge arrays of vias

    Folks, I do a lot of work pulling GDS files in from Virtuoso and simulating distributed elements. I generally draw two separate layouts -- one with all the via arrays conforming to the foundry design rules and another than contains large blocks of metal in place of the via arrays to speed up...

    Speeding up HFSS script for model creation

    I will give this a try. I've noted that if, prior to executing the script that builds the BCs, if I hide all the solids in the model in all views, the script is able to execute much more quickly (I'd say almost 100% faster). It still begins to slow down as the number of created BCs grows... -J

    Speeding up HFSS script for model creation

    SLK001 -- I don't believe this is the case. The machine I'm using (RHEL) has 512GB of RAM. The process that's building the model is using less than 15GB of RAM. -J

    Speeding up HFSS script for model creation

    Is there any way to suppress the UI re-drawing the model after each BC (or object) is created? -J

    Speeding up HFSS script for model creation

    Folks, I'm building a large structure in HFSS with thousands of periodically-placed lumped RLC boundary conditions. I can't use the eigenmode-solver and a smaller section of the structure because (1) it's an open structure, and (2) the distribution of the R, L, and C of the boundary conditions...

    HFSS transmission line perfectly-match terminations

    Folks, I am interested in simulating a series of slot lines and CPW transmission lines in a complex geometry (these lines are buried in layer dielectrics). I have a number of lumped impedance boundary conditions inside the structure to simulate active device response at a specific frequency...

    Angle of peak gain in HFSS?

    Folks, I'd like to be able to pull out the peak gain along a specific phi cut. That is, along a \[\phi_0\], I'd like the \[\theta\] corresponding to the maximum gain. Any ideas on how to do that aside from plotting a rectangular plot of the \[E_{total}\] along \[\phi_0\], loading that into...

    Using AnsysEDT over VNC -- BLACK windows

    Folks, I've been running AnsysEDT 16 on RHEL over VNC (using Tiger VNC on the server side, I've used a series of VNC clients on my desktop). When I attempt to build/modify an HFSS design, select a trace or insert a marker in a result window, the window turn black. I have to close the window and...

    ANSYS EDT 2015 HFSS HPC HFSSCOMENGINE hanging on Linux

    Folks, I'm using ansysedt on RHEL with an HPC pool license. I am simulating an HFSS model (driven) across a parametric sweep. The analysis is utilizing the direct solver with an interpolating frequency sweep. The analysis configuration is utilizing 40 cores with 10 tasks on the local machine...

    Dispersion curve along a longitudinal slot in HFSS

    PlanarMetamaterials, thanks for the reply. I would like to get the propagation constant from a driven modal model (i.e. the S parameters). The issue is that I'm looking for the propagation constant of the space leaky mode that's coupled from the slotline mode. If I setup a lumped parameter...

    Dispersion curve along a longitudinal slot in HFSS

    Folks, I'm looking for a method to generate the dispersion relationship (i.e. beta vs frequency) along a longitudinal slot on a traveling wave antenna. I've played with the HFSS fields calculator, but I've found it completely inexplicable. Does anyone have any experience in this area? Any ideas...

    HFSS/AnsysEDT HPC issues

    I'm running Ansys Electronics Desktop 2015 on RHEL 6. I've got a 48 core machine with plenty of memory and more HPC pool licenses (no pack licenses) that I can use. Whenever I configure a parametric sweep with an associated interpolating frequency sweep of an HFSS model and select anything more...

    ADS 2103, after adding 8HP PDK, no models available?

    Volker, RealAEL, thanks for the help. Any idea if the IBM 8HP has a full ADS PDK (vice the IDF PDK)? -J

    ADS 2103, after adding 8HP PDK, no models available?

    Volker, thanks for the reply. It looks like there are no components being loaded into ADS. The lib.defs file is as follows: # Library Defs for BICMOS8HP_IDF design kit DEFINE BICMOS8HP_IDF_tech ./BICMOS8HP_IDF_tech ASSIGN BICMOS8HP_IDF_tech libMode readOnly DEFINE BICMOS8HP_IDF...
