  1. Hello. I want to investigate the effects of putting two types of patch antennas on top of each other. I have followed the example guide on how to make a patch antenna using the planar Multilayer infinite substrate. If I were to want to put a second substrate and antenna on top of the example, is there anything I need to watch out for in order to ensure accurate results? Is it as simple as adding another substrate layer using the Planar Multilayer Substrate and drawing another patch on top?
  2. Hi, I did induction heating simulation in Flux2D . I try to define my substrates from isotropic to anisotropic on resisitivity - which means the Y-direction value become much smaller. Then I hit the solver but it says the it is not correctly converge. What can I changed to make it happen? Best, Jerome.
  3. Hi, Where to apply pretension force in pretension analysis in Optistruct. ? Middle of the bolt or tightening area or thread starting area? Pls find the image rgds, Arul
  4. I want to simulate an array of Vivaldi antennas, which is obviously very resource intensive. I have read that one can use DGFM to solve antenna arrays and that it will help to run the simulation faster, and with less memory requirements. However, I have also read that you cannot use DGFM with regions that use SEP for certain versions of FEKO and this error message is displayed to me when I run CEM validate in CADFEKO. I have updated my FEKO version - it is FEKO version 2018.2.1-343574 . Is this one of the versions that cannot use SEP and DGFM at the same time? If I cannot use DGFM to solve the array what other methods can I use to help lessen the amount of memory and time resources that is required to simulate the array? Is there a way to fix this? How does this FEKO version relate to FEKO 14 (since I read somewhere that in FEKO 14 this problem was fixed)?
  5. I want to run my simulation with explicitly UTD or explicitly PO. However, I don't understand the solver settings in 2018. In default settings, I don't have the option to only select UTD as the PO/MoM has to be selected on top.
