I am opening a file in CAESAR II. Within a few seconds of opening it within graphical view - CAESAR II crashes.

Is there a known issue with CAESAR II that could be causing this problem? What is the likely issue?

The CAESAR II file was converted using FEA Tools - adding several restraints.

Try switching graphics drivers - you can find this setting in the "Graphics pane" of the Configuration module.

If you continue to have issues, please file an SR on Smart Support.
