Error using HFSS SBR+


    • baccidavid
      Hi all, I have been trying to calculate monostatic RCS with SBR+ (PTD & UTD rays) of a delta wing. The model is 12 meters long and I try to do a full spherical analysis at 1.3GHz (which works fine) and one at 9.6GHz which always fails no matter what settings I change. I get no issues on meshing but only this message:

      [error] Project:v1, Design:HH (SBR+), Error solving SBR+ region! -- Simulating on machine: cmrc-cn02 (4:16:57 PM May 27, 2022)info] Project:v1, Design:HH (SBR+), Discrete frequency sweep complete. -- Simulating on machine: cmrc-cn02 (4:16:57 PM May 27, 2022)[error] Project:v1, Design:HH (SBR+), Sweep Sweep failed -- Simulating on machine: cmrc-cn02 (4:16:57 PM May 27, 2022)[error] Project:v1, Design:HH (SBR+), Simulation completed with execution error on server: cmrc-cn02. (4:16:57 PM May 27, 2022)

      Does anybody has idea what is happening?

      Please provide more information about your query to help us serve you better.
      May I know what sweep type you are using for the "sweep" in the error message? Try disabling it if not required as you already have a discrete sweep.
      Which version of AEDT are you using and what are the RAM and storage limits you have in your system?
      All the very best Praneeth.

      Hi Praneeth
      Thanks for your reply
      I am conducting a full scan in elevation and azimuth at one frequency (9.6 Ghz)
      The computation in performed on a 3 nodes cluster (each node has 64cpu cores and 384 Gb of ram)
      Interestingly, if i split the scan in elevation, in 4 sub intervals (from 0 to45, from 45 to 90, from 90 to 135, and from 135 to 180) the calculation goes okay
      Any guess?

      Ah sorry I forgot, version is 2022R1
