In addition to everything that's been mentioned, you should be using Floquet ports to excite the unit cell. After that, it's simply a matter of solving for the appropriate number of modes. This will be displayed in the modes calculator, and will vary based upon frequency, unit cell size, and...
These errors generally suggest something isn't set up quite right in your project. I suggest you contact your local ANSYS AE, and have them look at the project. If nothing else, then you need to post MUCH more detailed information here on the project and the error.
First of all, you are trying to use HFSS 11. ANSYS is now up to HFSS 15. I would suggest you upgrade your version as there have been many updates to the modeler over the years. Secondly, a non-manifold error occurs when some part of your object somehow intersects with another part of your...
This is what is going on most likely. There is a Linux Installation document found on the ANSYS Customer Portal @ support.ansys.com. I suggest you get this document, install all the dependencies, and you should be good to go.
1. When using solve inside, I would recommend adding a mesh seeding operation to "kick-start" the mesh in the conductor. Select the trace object, HFSS > Mesh Operations > Assign > Inside Selection > Length Based.
2. Uncheck "Restrict length of elements" and Check "Restrict Number of elements,"...
First of all, I think you've been mis-quoted on the price of HFSS. The product alone is not over $100k. I would recommend you speak with a local account manager for a more accurate quote.
Secondly, as I understand it, the principle method that FEKO uses is a 3D MoM solver. They might have an FEM...
@anvc - This sounds like a problem with mixed units or improper setup. A simple dipole should not take more than a couple of minutes to solve. Even though the structure may be large in physical size (17 cm), it should be reasonable in electrical size (lambda/2). Check to make sure your units are...
In HFSS, if you go to Tools > Record Script, and then change the files of type to Python, you will record your actions in a Python script. The syntax is almost identical between VB commands and Python commands as far as HFSS is concerned.
As far as Linux support goes, ANSYS does support both...
The *most accurate* way of solving this problem is to use the HFSS-IE solver in conjunction with the FEM solver to perfectly truncate the air region surrounding your antenna. This is the so-called FEBI method (Finite Element-Boundary Integral). Using the IE solver to truncate the region affords...
In addition to this suggestion, the Iterative solver in HFSS, when combined with the Mixed Order elements should be able to solve a corrugated horn very easily. In addition, you can add expressions, such as Gain, to control the convergence of the mesh in addition to the standard DeltaS criterion.
Generally speaking, you can replace extremely thin films in HFSS with either an impedance boundary condition or a layered impedance boundary. Consult the online help for more information. The issue with thin objects is not that HFSS won't do a good job of meshing the films. It is the fact then...
One other way to do this is to expand the polyline command in the model editor. From there you can see the individual Create Line segments. While you are clicking points to create a polyline, you can right-click in the modeler, and select Close Polyline. This will automatically close it and...
Regarding question 4 above, a lumped port is a specific case of a waveport. The sizing guidelines for the waveport are generally *only* for a microstrip/stripline type of excitation. You actaully *want* the lumped port to be electrically small. The way the port solver interprets a lumped port is...
The skin effect can be modeled explicitly in HFSS by solving for the fields inside the conductors. By default, the surface impedance approximation is used, and the field inside "good conductors" is set to zero. You can override this default, and "solve inside" the conductors. This will...
Yes. That is a correct statement. However, comparing a 3D FDTD solver to a 2.5 D MoM solver is comparing apples to oranges. A FDTD solver will require the mesh for the volume which the Planar solver will not. Both methods will allow the user to use a minimally sufficient mesh to get a fast...
