* Please don't change material parameters directly inside data directory,
data are chosen and used in the reference.py script launched by ctest.
If it is changed then reference results are not the same.
* How does restart work?
It is realised by the helper class PreProcessing. We assume that we
restart at step n. Several data are needed in order to restart:
- disp field (step n-1),
- phi field (step n),
- old phi field (step n-1),
- nonlocal domain (element only) (step n),
- computation mesh (if crack already appeared) (step n).
Things to know:
- disp field is step n-1 one, it is given as initial field to the
newton-raphson loop in Algorithm. If the problem is linear and
solved directly (elastic_damage is chosen), there is no need to
know this field, but it is loaded anyway.
- The computation mesh is exported using AOMD implementation which
exports in ASCII. Once reloaded, node locations slightly differ
because of the truncation of node coordinates. To test if restart
restores the exact same state, uncomment the two lines of code
in TLSGeom constructor
data.ReadMesh();
comp_mesh=data.mesh;
and comment
comp_mesh=new xMesh;
pre_pro.loadMesh("comp", *comp_mesh);
This test works only before the emergence of a crack (when d<1).
Without this modification, you cannot restore the exact same
solution unless you code a binary export/import of the mesh. Good
luck if you go for this!
- The integration mesh has to be rebuilt, as well as partitions,
it implies the regeneration of computation mesh sadly.
