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.

Using Homard in a non linear case and a few other remarks can be found
here
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
