Scripted simulations are predefined simulation scenarios, which provide a quick and easy way for you to test the network's resiliency to various failures. For each script, a failure report is automatically generated.
Before running a scripted, or batch simulation, be sure to review your failure simulation option settings. These can be accessed by selecting Tools > Options > Failure Simulation, and are described in detail in Failure Simulation Options. By default, an exhaustive failure simulation will fail all elements one for each simulation. To specify not to fail certain nodes or links, first modify the node (Design Properties tab) or link (Properties tab) and set FAIL=0 to true.
