Mesh refinement based on the Homard

In the contribution with links below mesh refinements are discussed. All the refinements are based on the Homard macro command MACR_ADAP_MAIL.

• In the first link 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 the second link the same object is refined during successive iterations. The Python loop mechanism is illustrated.
• In the last link the mechanism of the refinement is illustrated on a simple beam construction. The mesh refined is now based on the axial displacement of the beam. Very nice to understand how the mechanism operates.

Not really links, but nice to study are the examples

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