HE02153: ANALYSIS : REMOVE MESH: THE MESH IS NOT RECREATED WHEN THE MESH IS ACTIVATED/UPDATED AFTER PERFORMING REMOVE MESH.

APAR status

• Closed as Permanent restriction.

Error description

• SCENARIO:
  When the mesh is activated/Updated after performing Remove
  Mesh, the mesh is not recreated and error message appear.
  Error Message
  Impossible to mesh connection Mesh Part : Contact Connection
  Mesh.1
  Projection is impossible.
  Possible causes:
  1. Connection is designed to link 2 close geometries/meshes.
   - projection tolerance = 1.41421mm as result of internal
  computation based on meshes to connect.
   - Reduce distance between geometries/meshes to get a
  connection mesh
  2. Projection sources are projection targets
  3. No source to project.
  PROBLEM:
  The mesh is not recreated when the mesh is activated or
  Updated after performing Remove Mesh.
  EXPECTED RESULT:
  The mesh which is removed by Remove Mesh function, should be
  retrieved normally after Update mesh or performing Activate /
  Deactivate on mesh.

Problem conclusion

• THIS PROBLEM IS PERMANENT RESTRICTION IN CATIA
  Additional Closure Information:
  .
  INCIDENT DIAGNOSIS:
  The contact connection mesh cannot be updated successfully
  after performing Remove Mesh.
  .
  RESTRICTION EXPLANATION:
  In order to create a contact connection mesh, it has to be
  possible to project a node from one surface to other, meaning
  that the two surfaces should face each other.
  However the BR data (created on R18 level) contains two faces
  that do not face each other. i.e. a Node from surface 1
  cannot be projected onto the surface 2 with normal projection
  direction.
  On R18 level, it was possible to define contact connection
  even though there is no overlap between the two surfaces.
  However such result is physically not relevant.
  Therefore a new development has been done so that operator
  does not allow user to generate such FE model. In addition,
  whenever user updates such contact connection mesh (faces
  having no overlap between them) an appropriate error message
  is thrown to educate the user about the situation.  Please
  refer QA00000005264 to know more about the contact connection
  mesh.
  .
  By-pass:
  Move the geometry so that faces will overlap i.e. a node from
  one surface can be projected on to other.
