Dec 19, 2019 · If you mean you are using Mechanical Workbench, then in Mechanical, you go to Tool, Solve Process Settings click the Advanced button and type in 11 for Number of Cores. The output shows that the DB amount, >16GB, is larger than the total RAM available and I suspect larger than the virtual amount as well. DataModel. Likewise, AMD has CPU models and platforms ranging from 1 to 8! memory channels. 2. This is a recommended setting for you to look at, if your graphics do not look good, or if you are facing any issues with the basic navigation Since WB LS-DYNA is itself an ACT extension one has to retrieve the user solver object and then access the properties. Please increase virtual memory on your system and/or increase the workspace memory and re-run ANSYS. 1. One reason to change the default memory settings is when a job fails due to insufficient memory that may be caused by fragmented memory. In this case there is very little you can do.
