HD73272: DMUKIN: "KINEMATICS SIMULATION" IS NOT PERFORMED AFTER THE EDIT .

APAR status

• Closed as Permanent restriction.

Error description

• ABSTRACT:
  DMUKIN: "KINEMATICS SIMULATION" IS NOT
  PERFORMED AFTER THE EDIT.
  .
  SCENARIO:
  1. Launch CATIA V5R18SP3 & open the
  file "TEST.CATProduct" with DMU Kinematics w/b.
  2. Expand "Applications" on the tree. "Mechanisms"
  is displayed on the tree.
  3. Expand "Mechanisms" on the
  tree. "Mechanism.1, DOF=0" is displayed on the
  tree.
  4. Double-click "Mechanism.1, DOF=0". "Kinematics
  Simulation" dialog box is displayed.
  5. Input 135 to the "Command.1" cell. Do not move
  a slider.
  6. Click "Close".
  7. Double-click "Mechanism.1, DOF=0".
  .
  RESULT:
  "Kinematics Simulation" is not performed.
  A "Kinematics Simulation" dialog box is displayed.
  The message which cannot perform a simulation is
  displayed. The insufficient message of the joint
  command is displayed.
  .
  EXPECTED RESULT:
  "Kinematics Simulation" should be performed even
  if the numerical value was inputted directly in the
  cell of dialog box.
  .

Problem conclusion

• THIS PROBLEM IS PERMANENT RESTRICTION IN
  CATIA.
  Incident Diagnosis
  DMUKIN: 'KINEMATICS SIMULATION' IS NOT
  PERFORMED AFTER THE EDIT.
  Restriction Explanation
  The 135deg position is what we call a singular
  position. When exiting on this position and re-
  entering into the simulation command, the solver is
  not able to re-initialize the simulation anymore.
  This is a limitation of the kinematics solver.
  By-Pass
  You should stop at a position very close to 135 deg
  like 135.001 deg. Then the simulation can start
  again.
