    HFSS Hide coordinate systems

    I am working on a design with a coordinate system tree that has become very cluttered. Is there a way to hide them in the menu so that I don't have to scroll past hundreds of coordinate systems that Ill never use again to get to the more recently created coordinate systems?

    CST Asymptotic - field values at a position

    Is it possible to find the field values at particular locations using the asymptotic solver? I have a large reflector that I want to solve for, and I want to find the field intensity values 100 lambda, 1000 lambda etc away from the source. Field monitors make the solution much much longer, there...

    [SOLVED] [HFSS] MagE and CmplxE

    MagE is a complex number. "Mag" here indicates the vectorial magnitude, ie. sqrt(reEx+reEy+reEz)+i*sqrt(imEx+imEy+imEz) ComplexMag is a real number, and it is the absolute value of MagE. MagE is a complex number so it can be animated wrt time. ComplexMag is a real number, it cannot be animated...

    Grounded co planar microstrip antenna excitation in HFSS

    I never simulated GCPW in hfss but I know that "multipin waveguide port" in CST can make this easier, if you have the choice.

    [HFSS] What does N/A mean for delta S?

    No. Only the simple delta S criteria, only a single frequency adaptive meshing.

    Properties of material ( silver and copper )

    When you right click an object and say assign material, it brings up a window where you can find silver and copper along with many other materials

    [HFSS] What does N/A mean for delta S?

    I understand the first pass. But why the 8th pass? What possible reason could there be for delta S to be not calculated

    [HFSS] What does N/A mean for delta S?

    Sometimes the delta S value in HFSS is shown as N/A. What causes this?

    Can I define regions of different mesh sizes inside a polygon in CST MWS?

    Is the object 3D? You dont need any meshing for the interior of the PEC at all. I think CST skips the calculation for the interior of the object anyway, so there is no point in defining a coarser mesh. What kind of problem is this? What is the size of the object in wavelengths? What is the band...

    Creating a matching network for an HFSS antenna array in Ansoft Designer

    I solved it. If you go to the antenna Design, plot Directivity*RadiatedPower/(however much a single port is excited in circuit model, for my case 1^2/100) it will plot the true realized gain.

    What is the difference between "design variable" and "project variable" in HFSS

    Re: What is the difference between "design variable" and "project variable" in HFSS There is a project manager on the left. http://www.edatop.com/uploadfile/2014/0902/20140902051020167.jpg The variables when you click on Project1 are project variables, and you define them by using a dollar...

    Can I define regions of different mesh sizes inside a polygon in CST MWS?

    If you unite the geometries, the mesh definitions will be combined also. If you want to have different mesh densities for different parts, you must keep them separate. This will work fine for frequency domain and integral equation but it is more complicated for time domain. Are you using time...

    Creating a matching network for an HFSS antenna array in Ansoft Designer

    I believe doing "push excitations" calculate the correct amount of coupling between the ports and give the correct directivity. However, the feed losses (which are not in the antenna HFSS model, but modeled as a circuit in the circuit designer) are still not included in the Gain. The gain...

    Creating a matching network for an HFSS antenna array in Ansoft Designer

    I am able to import the HFSS model into circuit view, create a matching network, see how much return loss and coupling I have through the circuit analysis results. However, I am not able to see how the matching network changes the realized gain. I could do a "link output" for the gain, and...

    Forcing HFSS to ignore a certain region

    I want to force HFSS to not mesh a particular region in a model. The model that I have includes a multilayer circuit board that is not very relevant to the region that I want to simulate. It is acceptable to me if the entire multilayer circuit board is modeled as a block of PEC, which is exactly...
