v4.5
ab09a0c

Added

  • new mmg and parmmg (parallel mmg) plugins interfacing mmg5 and parmmg libraries, to replace mmg3d-v4.0 and freeyams (Thanks to P-H Tournier)
  • a true 3d anisotropic mesh adaptation examples/3d/Laplace-Adapt-aniso-3d.edp
  • an example to extract surface mesh from isovalue in examples/3dSurf/Pinochio.edp
  • function f.eatspace to reach eof on istream file which return false in case of EOF.
  • function f.length to get the istream file length
  • Interface to PetscLogStagePush()/PetscLogStagePop()
  • Ability to directly assemble a Mat using a varf
  • New bem plugin for the Boundary Element Method (using htool and BemTool libraries)
  • New DSL for BEM (varfbem see examples/bem)
  • add int0d to apply Neumann BC (curve FE), differential operators (dx,dy,...), compute an 1d integral
  • add P1dc FE for Border FEM (possible to define a new FE with plugin)
  • PETSc as a subdomain solver for HPDDM

Changed

  • correct ffglut (bug in case of changing number of nb isovalue)
  • PETSc version 3.12.4
  • Change the point search triangle algorithm to be sure in any case (in test)
  • Sline operator renamed to segment
  • In square3, segment, movemesh functions: geometry transformation can now be [X] or [X,Y] or [X,Y,Z] according to the minimal shape element dim
  • PETSc now download OpenBLAS if there is no BLAS found by FreeFEM configure

Deprecated

  • freeyams plugin
  • mmg3d-v4.0 plugin

Fixed

  • fix plot for curve mesh
