I have 128 GB memory on the node distributed on 20 cores. I have allotted 16 cores for the solution and am expecting a minimum of ~90 GB memory available for it. However, in the solution output file reads <strong>Maximum total memory allotted is ~ 30GB and Total physical memory available is 126GB<\/strong>.<\/p>\n<p>When I include (-m value (mb)) command in the Ansys command line I get Error stating: <strong>The memory (-m) size requested [value mb] is not currently available.&nbsp;&nbsp;Reenter ANSYS command line with less memory requested.<\/strong><\/p>\n<p>My eigen solver requires more than 32GB memory to converge to a solution.
