DGFM errors, SEP, FEKO 2018

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)?

    Hi Eliz

     

    DGFM+SEP is supported from 14.0.430. However, CEM validate was not updated to reflect this change. This bug will be fixed soon.

     

    You can ignore CEM validate errors for this in 14.0.430 and later.  I would recommend you upgrade directly to version 2019.

    As far as I know there is a bug in Feko 2018.2 and 2018.2.1 (fixed in Feko 2019) that causes an error when using DGFM to solve SEP regions (I responded in the duplicate thread).  I would also recommend you upgrade to the latest version of Feko 2019.
