Solver Out of Memory Error in HFSS

      Hello, I'm designing an antenna using HFSS, when i start analysing the set up(Parametric Analysis) , a 'Solver out of Memory,Verify your Ram limit' error appears , although my PC has 20 GB RAM limit ,has an enough availabe storage too and has 4 cores.

      I checked the HPC Options and the RAM limit is set to 90% and the cores up to 10 cores, but  the solution data shows that the RAM limit is only 9% and it is only 1 core as shown in the figures below,  so how can i solve this problem,since I've tried changing the frequency ranges but still the same error appears.

      For your Free Space Radiation boundary, are you using PML ?

      Hi Jana, Please note that the number of cores should match the available cores on your system. Also try reducing the distributed variations to 4 as you have only 4 cores available. Best regards, Praneeth.
