The Calculations page of BlockSim/RENO's Application Setup contains default settings that will be applied to calculated results when you create a new diagram or analysis in BlockSim or RENO. Note that some of the configurable settings that are saved with the diagram/analysis can still be modified from the control panel and others can now be modified via the Item Properties window.
Precision to be Displayed on Calculations sets the math precision (number of decimal places) and the point at which the software will switch to scientific notation. For example, if the scientific notation tolerance is set to 5, then any number that is larger than 105 will be displayed using scientific notation.
Precision for Convergence Criteria sets the tolerance that will be used as the convergence limit (degree of accuracy) for mathematical iterations (e.g., a value of 4 indicates 1E-4 tolerance).
Fault Tree Tracer Options sets the maximum number of blocks to read and maximum percentage of memory to be consumed by the fault tree tracer utility. The trace will terminate when any of the specified maximum values are exceeded. Setting lower values can help prevent out-of-memory issues. The memory threshold must be a value between 0 and 1, where 1 indicates no limit).
Other Options
Use identical block simplification by default for new diagrams. Select this check box to use identical block simplification (IBS) for analytical diagrams. When IBS is used, the software looks for blocks with identical failure characteristics and attempts to simplify the equation, if possible, when analyzing the diagram. This is useful when analyzing large diagrams that contain a lot of the same blocks. You can also select to use IBS from the analysis settings page for analytical diagrams.
Use mean time for the exponential distribution. By default, lambda is used as the scale parameter of the exponential distribution. Select the check box if you prefer to use MTTF (1/lambda) instead.
