Added

  • Bilaplacian example using Morley FE with PETSc, see examples/hpddm/bilaplacian-2d-PETSc.edp
  • Oseen problem preconditioned by PCD, see examples/hpddm/oseen-2d-PETSc.edp
  • SLEPc polynomial eigenvalue solver PEPSolve()
  • add trivail example to check periodic boundary condition on meshS , meshL , mesh3
    examples/3d/periodic3.edp examples/3dSurf/periodicS.edp
    examples/3dCurve/periodicL.edp

Changed

  • PETSc version 3.14.2
  • Mmg version 5.5.2
  • link of ffglut so change in configure.ac and Makefile.am LIBS -> FF_LIBS and LIBS become empty
    to remove default libs
  • change number of save plot in ffglut from 10 to 20 for O. Pironneau

Fixed

  • some memory leaks
  • the periodic boundary condition have wrong before first a sementic level of MeshS and MeshL case.
    the new syntexe is for example:
    meshL Tl=segment(10); fespace Vl(Tl,P1,periodic=[[1],[2]]);
    meshS Th=square3(10,10,[x2pi,y2pi]); fespace Vh2(Th,P1,periodic=[[1,x],[3,x],[2,y],[4,y]]);
  • fixed '*' keyboard trick, to keep the viewpoint in ffglut or not.
