Memory Management

Femap Tips and Tricks: A simple setting change will cause Femap's cache to use less memory.


Editor's Note: Welcome to the first in a new series of finite-element analysis tutorials. In addition to these written tutorials, author Alastair Robertson will also present each tip in video format — check each tutorial for a link to the associated video. This tutorial (and associated video) appear courtesy of Siemens PLM.

When Femap starts to run out of memory, it will issue a message urging you to save your model and to reconfigure to use less memory. How do you overcome performance problems that can arise through memory shortage, particularly when you are building large models?

To access Femap's memory management controls, select File Preferences and click on the Database tab. In the Preferences dialog you'll see a slider in the Database Performance section that controls the Database Memory Limit.



If you turn this setting down, Femap's cache will use less memory and rely more on swapping to the scratch file. This will decrease the amount of RAM being used and make things run faster.
