  1. 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)?
  2. Hi, I wonder if we can use variables in a custom template for FE out, beneath a small example. How does one set the variable properly? set $Variable = 22, in the output the last column is 0. second issue: I want to write the element and node amount to the file, I know that the "elements" and "nodes" returns a array: how to get theirs size and write it down? *components("","") *before() *string("#components") *end() set $Variable = 22 *format() *fieldright(integer,id,8) *string(" ") *fieldright(integer,elements,8) *string(" ") *fieldright(integer,nodes,8) *string(" ") *fieldright(integer,$Variable,8) *end() *output()
  3. Error 37389: DGFM is only supported when solving the linear equation system in main memory I keep getting this error when trying to use DGFM to solve a Vivaldi array. The array has only 2 elements but it seems as thought it is very resource intensive. What exactly does this error mean? What can I do to fix it? Does it have anything to do with the other problem of trying to use DGFM in conjunction with SEP for dielectric regions or is it a separate problem altogether? Is there a better way to simulate a finite array?
