      Bug correction in exportOnSpace · 9d0cd807
      Benoit LE authored
      Corrected parenthesis bug in exportOnSpace function, in the version which is
      used to export xTensor2.
      Remark : It was quite surprising that the code could even
      compile before ...

      Added a toExport function to PostProcessing · b769d03c
      Benoit LE authored
      May be useful if exporting a certain quantity requires some computations, but
      we want to do these computations only in the case where this quantity is
      supposed to be exported.

      Revert "Splitted updateMaterialVariables into two functions: updateMaterialVariablesFromLevelSet can be used to deal with any internal variable which depends on the level set (not only the damage variable), updateMaterialVariables must then be used to update the other material variables (like eps_ref for instance)"

      Mainly adapting to new FM interface to treat GAMAIN and avoid prb · 89ca0c12
      Alexis SALZMAN authored
      Adapting to para version
      Modify groups (sm, sub mesh) to enter FM with known fixed and volatile
      values. This is following new FM interface. It correct bug with previous
      interface where progression of the front was stopped by re-initialisation
      process (all new variation of phi removed by fast marching).
      Now buildBndIntNonlocal (TLSGEOM) is creating 2 set (bnd_part_nonlocal
      and bnd_nonlocal) in replacement of the original bnd_nonlocal. Those
      sets split boundary of non local zone in :
      * boundary with local mesh element (bnd_nonlocal)
      * boundary with part boundary (bnd_part_nonlocal)
      Has before it is do_bnd_in that control if we create bnd_part_nonlocal or
      not by calling GetBoundary or GetInteriorBoundary.
      In GetBoundary a dirty hack is used to identify part boundary and remove
      When do_bnd_in is 0 bnd_part_nonlocal exist but is empty.
      For FM, bnd_part_nonlocal is used has known volatile value. Says those
      part boundary value may or may not be re-initialized by FM. In the
      latter case those values are used for velocity computation as new extra
      modes with their values unmodified. This imply that on part
      boundary the level set live its own life when phi gradient enter the
      Unfortunately as can be seen, for now, in new dam_gamain test, setting
      bnd_part_nonlocal as volatile values may stop progression of the front
      just like before when all modified values are reset by FM.
      N. Chevaugeon suggested to create only volatile values for non modified
      values (values not updated during current time step). This look like a
      promising solution because removing these values from bnd_part_nonlocal
      and put them in bnd_nonlocal force them to be still present in velocity
      computation. It ensure that variation of phi is not destroyed. But it
      does not insure anymore that phi gradient norm is 1 around those values.
      This somehow must be the case when gradient direction start to be collinear
      to part boundary. In that case epsilon_ratio was supposed to do the job
      but for rather blunt variation of phi it is not clear if this will fits
      ours needs. So filtering like that bnd_part_nonlocal seems interesting.
      About epsilon_ratio it have been forced to zero because really strange
      result where obtain with it (non same result in case where
      bnd_part_nonlocal is empty, non deterministic computation !???).
      To be analyzed.
      This test case is to check if and how gamin feature works.
      It is a simple plate with a shear loading that force creation of crack
      with an angle of -45 degres (x axes). A default( removing of 2 elements)
      is placed in the diagonal of the plate a little closer to left upper
      corner. Mesh is regular and chosen to intentionally offers a line of
      nodes from default to corner. lc is chosen rather big so that number of
      element per lc is important.
      Without gamin non-local zone progress toward corner. When reaching
      part boundary modification of phi on it are clearly done by FM re-init only.
      It arrive to a point where bluntly in on step all corner is extra damaged (phi>lc).
      With gamain when reaching part boundary modification comes clearly from
      phi update in far more slower way. Crack continue on the diagonal.
      Unfortunately process is stopped by the case of delta-phi removed by FM.
      (see above for perspectives)
      In both case it is not clear how boundary condition have to be handle in
      omega+ zone. Without treatment like here it impose force on almost
      damaged material which induce maybe other estimate strain. To be check.

      Roll back to a unmodified version: only comment and basic para stuff present · 4852422c
      Alexis SALZMAN authored
      Modification, mainly buf_nodal_vec passed into a xDistVector and declare
      state in parallel are removed. This version have minimal change to work
      in // context with only one proc. Many comment are present to explain
      what have to be changed to work in distributed context. The previous
      commit have been tagged (WITHMODIF) to be able to get back to it when we
      will try to pass in distributed context.
      Many guard are present. They will be efficient to avoid mistake. Many
      other guard with comment are missing but this work will be done only if
      we pass in distributed context.
