If you look at the end of the solver output file, you will see a summary of the time and memory statistics. The Total CPU time for the main thread is let’s say ‘x’ seconds, while the elapsed time is ‘y’ s. This indicates that around y-x secs was spent on non-CPU activities e.g. swapping to disc or writing out result files. The warning is for information only and will not affect your final results. To improve the performance, you could consider using a machine with more RAM, or reducing I\/O operations. One option for the latter would be to reduce the frequency with which result data is written. You might be writing results at every substep (OUTRES,ALL,ALL). If you only need results at the end of each load step, you could use OUTRES,ALL,LAST or select them as needed from under Analysis Settings>Output Controls Additionally, please refer to Chapter 6 or the Performance Guide to read about this: https:\/\/ansyshelp.ansys.com\/account\/secured?returnurl=\/Views\/Secured\/corp\/v193\/ans_per\/per_measuring.html<\/p>\n","protected":false},"template":"","class_list":["post-162073","topic","type-topic","status-publish","hentry","topic-tag-2019-r1","topic-tag-general","topic-tag-mechanical","topic-tag-structural-mechanics"],"aioseo_notices":[],"aioseo_head":"\n\t\t\n\t\n\t\n\t\n\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t
