HD79863: ERROR IN WARP/WEFT ANGLE AND WARP/WEFT RATIO HANDLING. .

APAR status

• Closed as program error.

Error description

• Error in Warp/Weft Angle and Warp/Weft Ratio
  handling.
  See attached ppt for more explanation. and .zip for
  necessary data to reproduce the problem.
  The scenario is :
  Set the environment variable
  CATCompositesWarpWeft=1
  Set up the attached test framework in RADE R18
  and run CATIA V5
  Set breakpoint as shown
  void
  SLTEFmpFiberMeshOperator::SetBiaxialMaterialPara
  meters(const
  double iWarpWeft, const double iMaxStrain, const
  double iWarnStrain )
  Open the attached CompositesCatalog.CATMaterial
  verify that material WWA60 has a Warp/Weft Angle
  set to 60 deg
  verify that material WWA60 has a Warp/Weft Ratio
  set to 2 in the
  Composites tab.
  Open the attached AFM_02
  _sphere_with_darts_b.CATPart
  verify that ply
  Stacking/Undarted/Sequence.1/Ply.1 - AFM
  references
  material WWA60.
  Error 1: Parameter Value Wrong, as seen, the
  value of the Warp/Weft
  Ratio is wrong: it should be 2.0 not 1.0
  Error 2: Warp/Weft Ratio wrong The Weft Mesh
  Parameter should be equal
  to the Warp Mesh Parameter DIVIDED by the
  Warp/Weft Ratio. As the
  material value is 2, a 5mm warp value should
  mean a 2.5 mm weft value
  Error 3: Wrong iWarpWeft in
  SetBiaxialMaterialParameters Press Apply to
  run produciblity and stop at breakpoint set earlier
  iWarpWeft should have the material value of 60
  and not 90
  .
  

Local fix

Problem summary

• Error in Warp/Weft Angle and Warp/Weft Ratio handling.
  Set
  the environment variable
  CATCompositesWarpWeft=1
  run CATIA
  V5
  verify that material WWA60 has a Warp/Weft Angle set to
  60 deg
  verify that material WWA60 has a Warp/Weft Ratio set
  to 2 in the
  Composites tab.
  verify that your  ply
  references the  material ( WWA60).
  Error 1: Parameter Value
  Wrong, as seen, the value of the Warp/Weft
  Ratio is wrong: it
  should be 2.0 not 1.0
  Error 2: Warp/Weft Ratio wrong The Weft
  Mesh Parameter should be
  equal to the Warp Mesh Parameter
  DIVIDED by the
  Warp/Weft Ratio. As the material value is 2, a
  5mm warp value should
  mean a 2.5 mm weft value
  Error 3:
  Wrong iWarpWeft should have the material value of 60 and not
  90
  Wrong iWarpWeft should have the material value of 60 and not
  90
  

Problem conclusion

• THIS PROBLEM WILL BE FIXED ON   VERSION V5R20 GA
  level.
  Additional Closure Information:
  THIS PROBLEM WILL BE
  FIXED ON CATIA VERSION
  5 RELEASE 20 Beta LEVEL.
  Additional
  Closure Information:
  The issue has been fixed.
  You have to
  load your CATPart after you do
  "Tools->Option->MechanicalDesign->CompositesDesign->Check the
  option
  "Load Material catalog along with the CATPart".
  Now
  You will see cross mask on Composites parameters node & on
  material node which implies that the material properties is
  not
  synchronized with the current part.
  You can do
  sychronization or update so that the  issue is solved.
  

Temporary fix
