Please notice the release of a new document : "Mesh adaptation in non-linear analysis" U2.08.09 (automatic translation).

The aim is to give some advice to a user wishing to perform mesh adaptation in non-linear analysis.

The differents operations are presented:

  • resolution on one or more steps of loading;
  • mesh adaptation based on error indicator;
  • projection of the fields at the end of last time step on the new mesh;
  • balancing of the fields at the end of last time step on the new mesh.

An example of practical implementation is presented in the test case SSNP158
v6.03.158 (automatic translation).
