HD52321: FACTORIZED MATRIX COMPUTATION ERROR ON USING RIGID SPRING VIRTU AL PART

APAR status

• Closed as program error.

Error description

• FACTORIZED MATRIX COMPUTATION ERROR ON
  USING RIGID SPRING VIRTUAL PART
  .
  SCENARIO (Refer the ppt for more details)
  1.The following specifications are defined: Analysis
  Connections,
  Properties, Restraints, Loads.
  2.Read "Error_TEST_R16 xxxxx.CATAnalysis"
  3.Modify global mesh size value from 6.26 to 6.25
  in OCTREE Tetrahedron Mesh1:Part1/Nodes and
  Elements.
  4.Click Compute icon, and select the All option in
  the Compute dialog box and click OK.
  5.As a result an error dialog box below appears,
  and computation stops.
  .
  PROBLEM: Factorized matrix computation Error on
  using Rigid Spring Virtual Part
  This problem is regression versus R16SP3.
  (R16SP3:OK/R16SP4:KO)
  Spring analysis performs this analysis operation to
  suspension parts. It means that this cannot
  perform analysis calculation of a suspension.
  .

Problem conclusion

• THIS PROBLEM WILL BE FIXED ON CATIA VERSION
  5 RELEASE 17 GA level.
  NOTE THAT THIS PROBLEM WILL ALSO BE FIXED
  ON V5R16SP05.
  .
  Incident Diagnosis
  We have a factorized matrix computation Error on
  using Rigid Spring Virtual Part.
  The Rigid Spring Virtual mesh part has a node
  different with second node of null size bar that
  modelize the point support. This node generete a
  singularity.
  .
  Correction Explanation
  We do a correction on models to supress the bad
  creation of node that generate the singularity.
  .
  Answer and By-Pass
  no
  .
  

Temporary fix
