Six Sigma (Probabilistic) Analysis

Simulation often begins with specified deterministic values for dimensions, loads, boundary conditions and material properties.  However, in the real world, these values often vary due to manufacturing tolerances or the range of operating conditions. A Six Sigma analysis runs a series of small variations on these inputs and calculates the expected output variation. This can help you to determine whether or not your design meets robustness requirements.
