2. Define the fatigue parameters.
   1. Select SPOT or SEAM as the weld type.
   2. Select the FE model units.
   3. Select a mean stress correction option.
   4. Based on the scatter of the SN curve, enter a real value between 0 and 1 for the certainty of survival.
   5. Select Yes or No for thickness correction.
   6. Enter a value for No of Angles on Sheet.
      Note: This option is only available for spot weld analysis.
