Error description

• GPS : The maximum 'Von Mises Stress' value is not
  changed even if Young modulus balue has been
  changed.
  .
  SCENARIO:
  1) Open the provided CATAnalysis into GSA
  Workbench
  RESULT:
  Value of maximal VM stress is 2.84654E8 N_m2
  2) Double-click on the CATPart.
  Workbench is changed to 'GSD'.
  3) Double-click 'Steel'.
  4) Select 'Analysis' tab and change the value
  of 'Young Modulus' into 1N_m2.
  5) Click 'OK'.
  6) Double-click 'Finite Element Model.1'.
  7) MB3 on 'Von Mises Stress.1' and
  select 'Activate/Deactivate' by context menu.
  8) Click 'OK'.
  9) MB3 on  'Extrema' and select 'Local Update' by
  context menu.
  PROBLEM:
  The maximum 'Von Mises Stress' value is not
  changed.

  Incident Diagnosis
  The maximum Von Mises Stress value is not
  changed even if Young modulus value has been
  changed
  .
  Correct Application
  The maximun stress in this case is :
  sigma = Mf / ( I / v )
  where :
  Mf is the bending moment
  I the inertia
  v the maximun distance to the neutral fiber.
  This is independant of the Young modulus.
