Table Barrier Failure

In some cases, rather than entering a custom failure distribution by directly specifying the Fraction Failed, you may wish to use an external function to specify the custom failure distribution. This may be useful, for example, if the failure distribution is relatively complex and varies from realization to realization.

To facilitate this, GoldSim allows you to define a failure distribution by entering a link representing a 1-D Table Definition. External elements can produce special outputs representing look-up tables.

The Table Definition for a failure mode must be a 1-D Table Definition output produced by an External element. The independent variable for the table must have dimensions of time (which represents the Effective Time for the failure distribution), and the dependent variable must be dimensionless. In addition, the dependent variable for the table should must be greater than or equal to 0 and less than or equal to 1, and can never decrease as a function of time.

Note that if the table terminates at a Fraction Failed which is less than 1, GoldSim does not extrapolate the table (i.e., barrier failure is assumed to stop).
