The following table describes the differences you might see when you recalculate a Project converted from an earlier version to Relex 2009.

Module	Affected Calculations
OpSim	Simulated results differ. In Relex 2009, Relex RBD and OpSim are combined into one comprehensive and power-packed OpSim module. For more information, see RBD/OpSim Redesign.
Reliability equation is cleared by default. This means that unless you have selected this checkbox, the analytical equation used to calculate reliability is not shown on the Reliability Equations Results page under OpSim in the View Calculation Results window. This checkbox appears on the General page for OpSim calculations in the Calculate window. For more information, see RBD Calculation Properties.
