Full Changelog: https://github.com/MmgTools/mmg/compare/v5.7.2...v5.7.3

This patch fixes various errors when building and executing Mmg with int64 integers.

This patch fixes:

• erroneous release date
• issues in the FindMMG<X>.cmake files (provided to help library users to find Mmg)
• a wrong installation path

What's Changed

• [CMake] Correct release date in CMake by @loumalouomega in https://github.com/MmgTools/mmg/pull/193
• [CMake] Correcting last versions of CMake modules by @loumalouomega in https://github.com/MmgTools/mmg/pull/194

Full Changelog: https://github.com/MmgTools/mmg/compare/v5.7.0...v5.7.1

This release includes:

• modifications of the Mmg install tree and CMake build (a clean build and install will be needed). Be careful, the USE_SCOTCH, USE_ELAS and USE_VTK, CMake variables behaves differently than in previous Mmg versions
• the possibility to build Mmg using 64 bit integers to handle larger meshes
• the new -lssurf option to split mesh boundaries along an isovalue while preserving only 1 volume domain
• the new -isoref option to choose the reference of the inserted iso-surface in level-set discretization mode
• the possibility to remove parts of the implicit domain that are not connected to boundary conditions listed in input parameter file
• the possibility to provided non-bijective multi-material maps in level-set discretization mode (at your own risks)
• the preservation of input ridges in level-set discretization mode
• the new -xreg option to smooth position of boundary vertices
• improvement of the gradation process in Mmg3d (-hgrad option)
• support of shared library compilation on windows
• bug fixes.

This release includes:

• various bug fixes;
• the robustification of isosurface discretization, more particularely in multi-material mode;
• internal modifications of the analysis to support the parallel surface analysis in ParMmg;
• a new possible argument for the -3dMedit command line argument: now -3dMedit 3 allow to pass from a 2D mesh saved in 3D into a "true" 2D Medit file.

This release includes:

• various bug fixes;

• internal modifications of the analysis to support the parallel surface analysis in ParMmg;
• a new possible argument for the -3dMedit command line argument: now -3dMedit 3 allow to pass from a 2D mesh saved in 3D into a "true" 2D Medit file.

This release patch fixes:

• a memory error and a bug when using Scotch in Lagrangian mode (mmg3d);
• an error when splitting boundary edges in lagrangian mode (mmg3d);
• a regression when computing the available memory on large memory computer (mmg3d);
• a possible NaN creation in optimLES mode.

That patch fixes:

• compilation errors when building on platform where char is unsigned (ARM for example)
• a regression in isovalue discretization mode (leading to topological errors)

This release includes:

• the possibility to preserve input references when discretizing an isovalue with mmg3d (multi-material mode);
• the possibility to discretize an isovalue and to adapt over a metric in one mmg call (modification of existing APIs);
• the new -rmc option that allows to remove small parasitic components within an isovalue in isovalue discretizat ion mode (bubbles removal);
• the preservation of input quadrangles in Mmg2d (modification of existing APIs);
• the possiblity to impose local parameters in Mmg2d;
• the preservation of points given as required even if not connected to the mesh;
• the new -nsd option that allows to save only one domain of a multi-domain mesh;
• the renaming of the -msh option into the -3dMedit one (modification of existing APIs);
• new I/Os (VTK file formats .vtk, .vtp, .vtu) and new outputs (Triangle and Tetgen file formats .node, .ele, .face, .edge, .neigh);
• the new -nreg option to enable normal regularization;
• the migration to Modern CMake;
• new preprocessors macros to help user to detect Mmg version.

It provides new API functions :

• MMG[2D|S]_Get_numberOfNonBdyEdges and MMG[2D|S]_Get_nonBdyEdge to get non boundary edges (for example for DG methods);
• MMG3D_Get_numberOfNonBdyTriangles and MMG3D_Get_nonBdyTriangle to get non boundary triangles (for example for DG methods);
• MMG2D_[S|G]et_quadrangle to provide quadrangle to mmg2d;
• MMG[2D|S|3D]_GetByIds_vertex to get a vertex from its index;
• MMG[2D|S]_Get_triangleQuality to get the quality of a triangular element;
• MMG3D_Get_tetrahedronQuality to get the quality of a tetrahedron;
• MMG[2D|S|3D]_Compute_eigenv function to compute eigenvalues and eigenvectors of an input metric tensor;

It also modifies some existing API functions :

• MMG[2D|S|3D]_mmg[2d|s|3d]ls functions now takes a third argument, the input metric (may be null);
• MMG2d_[S|G]et_meshSize functions takes a new argument before the number of edges, the number of quadrangles (may be 0 or null).

This patch fixes:

• Errors in fortran API
• Wrong definitions for functions pointers
• A possible integer overflow
• Various problems in the cmake usage

It allows to position manually the M_LIB variable to specify the libm location.
