  1. I'm using an older version of FEKO for an ongoing study and would prefer not to update until the study is complete. Does FEKO have an automatic update/hotfix system, or do updates and hotfixes have to be implemented manually? Thanks!
  2. I have a pretty simple question about creating dielectric media in FEKO: Does the density of the media have any effect on the simulation other than the calculation of specific absorption rate? I'm working under the assumption that if I'm not interested in the specific absorption rate for a model, then I need not worry about the density of the dielectric media, provided the dielectric properties are accurate.
  3. Thanks tinh, Would you be able to direct me to what feature in HyperMesh can be used for this?
  4. I am having an issue where I establish a wire port using the 'middle' option for the port's location. It appears in the center of the wire as it should in CADFEKO. However, once the meshing is complete, the port has moved all the way to one end of the wire. This is reflected in the POSTFEKO geometry as well. Does anyone know what might cause this sort of behavior?
  5. Thank you, mel. However, although the manual mentions both a 'no internal impedance' and 'internal impedance' options for 'total source power', when I select the 'Power' icon under the 'Source/Load' tab in CADFEKO, there are only three options: No power scaling Total source power (no mismatch) Incident power (transmission line model) Is there a way in CADFEKO to access the additional internal vs no internal impedance settings? If not, do you know which is used by default? I'm using a 2018 version of FEKO.
  6. Thank you mel. I have moved my discussion to the HyperMesh forum.
  7. Does HyperMesh have a feature that would allow you to essentially wrap a thin mesh (like a sheet of paper) around a complex structure (like a the body of a car or something)? I am interested in running FEKO simulations on a flexible antenna that is essentially wrapped around its mounting point. I have not yet started using HyperMesh and am evaluating my options to accomplish this task, so I apologize if this question is overly simplistic.
  8. I'm trying to understand the difference between "Total source power" and "Incident power" settings when using power scaling in FEKO. My confusion arises from noticing that 'mismatch loss' and 'power loss due to mismatch' are still available analyses in POSTFEKO and are non-zero. I assume that these analyses are referring only to the amount of power that would be lost to mismatch, not how much power was actually lost? I am doing specific absorption rate studies and would like to produce a conservative estimate using the 'Total source power' setting.
  9. Is there a way in FEKO or in HyperMesh to wrap a flat mesh (for example, a thin cuboid), around a complex object so that the two meshes are in direct contact?
  10. Thanks for the info. That helps a lot!
  11. I'm trying to model a real antenna with a similar feed structure to that shown in the attached photo. Right now, I am modeling the feed as a perfect conducting wire between the two leads with a voltage source feed point at the middle of the wire. The antenna itself is modeled as a finite thickness region, that is, having four sides in three dimensions. Without explicitly modeling the feed wires of the real geometry, does anyone know of a more accurate way to model the feed? I am interested in evaluating the antenna's specific absorption rate (SAR). It is meant to be placed directly on the skin.
  12. Is it possible to create an infinite dielectric object in FEKO? That is, an object with a defined upper Z direction boundary, but terminating at -infinity in the Z direction and infinite X and Y dimensions.
