Mesh refinement based on the Homard

In these contributions (links below) mesh refinements are discussed. All the refinements are based on the Homard macro command MACR_ADAP_MAIL.

  • In link 1 the mesh refinement is based on a stress error estimation. The refinement are performed for the elements with the highest stress error estimation. The geometry is an L shaped steel object with a number of holes in it.
  • In link 2 the same object is refined during successive iterations. A Python loop mechanism is used to perform successive iterations.
  • In link 3 the mechanism of the refinement is illustrated on a simple beam construction. The mesh refined is based on the axial displacement of the beam. Very nice to understand the mechanism of the refinement.

Not really links, but nice to study are the examples

  • zzzz121a.comm,
  • zzzz121b.comm,
  • zzzz121c.comm,
  • zzzz121d.comm and
  • zzzz121e.comm.

in the astest directory [$ASTER_ROOT]/STA[$VERSION]/astest/.....,
e.g in my case: /cae/aster101/STA10.1/astest/zzzz121a.comm
