v5.2.1

Patch regression in computational time due the local parameters evaluation.

v5.2.0

This release adds :

• input and output files at gmsh format;
• the reading of normals at boundary vertices for mmg3d and mmgs;
• the isovalue discretization for the mmgs software and library (MMGS_mmgsls API function);
• the -default option that creates a file containing the default parameters of Mmg. By modifying this file, you can impose local parameters (hmin, hmax, hausd) over different boundaries;
• the -octree option replace the -bucket one but it is not mandatory anymore to precise the octere size;
• a true fortran API and C++ API;
• new API functions to set/get the mesh entities (vertices, elements, boundaries) by arrays;
• FindMmg*.cmake files to help users to find the Mmg libraries using CMake.

It modifies the mmg3d library API:

• the MMG3D_Set_meshSize and MMG3D_Get_meshSize functions takes two additional arguments to be able to read prisms and quadrangles.

5.1.4

Patch error in the memory count in mmg's API: at memory allocation, if the mesh was already allocated we were freeing it with a wrong number of poits/edges/elements...

v5.1.2

Remove the MMG3D_DPARAMETER_ls parameter from the mmg3d API because this option is not implemented for now.

v5.1.1

This hotfix :

• Patch a bug in mmg3d with 0 verbosity (the tetra qualities were not computed);
• Correct a wrong point index in mmg3d colver function (when updating the surface edge tags).

v5.1.0

Release/5.1.0

This release adds :

• the mmg2d application and library (for bidimensional mesh generation and isotropic/anisotropic mesh adaptation);
• the anisotropic mesh adaptation for mmg3d and mmgs;
• the mmgs library (API + mmgslib function);
• the mmg3dls library function corresponding to the -ls option of mmg3d (allow to discretize an implicit surface);
• manpages for the mmg2d, mmgs and mmg3d application (available in the doc/man directory).

It modifies the mmg3d library API:

• the API functions are now prefixed by MMG3D instead of MMG5;
• the 'MMG3D_Init_mesh' and 'MMG3D_Free_all' functions takes now a variable number of arguments. Please, refers to The documentation to see how to call it;
• the 'MMG5_loadMesh/saveMesh' functions are replaced by the 'MMG3D_loadMesh/saveMesh' ones that takes an additional parameter: the input our output name of the mesh file;
• the 'MMG5_loadMet/saveMet' functions are replaced by the 'MMG3D_loadSol/saveSol' ones that takes an additional parameter: the metric file name.

It modifies the 0 verbosity that don't print anything now.

It modifies the treatment of the input boundaries in mmg3d:

• if no triangles are provided, the boundary triangles are created with the reference of the associated tetrahedron (if the triangle is at the interface of 2 domains with different references, we take the minimum of the 2 refs);
• if some boundary triangles are provided twice, they are deleted;
• if some boundary triangles are missing, they are created with the reference of the associated tetrahedron (and the provided triangles are preserved);
• if triangles at the interface of 2 domains with same reference are provided they are deleted.

v5.1.0-beta5

This hotfix patch:

• a bug in the edge searching process in mmg2d;
• a bug in the quality computation of the worst element in mmg2d;
• a bug in MMGS_Set_meshSize function (thank to updega2 that correct this error);
• an error in the reading of the normals an ridges in mmgs (for ascii files).

It cleans:

• the mmg2d verbosity;
• the libraries headers.

v5.1.0-beta4

C++ compatibility using "extern "C"" keyword.

v5.1.0-beta3: Fix a bug in the mmg2d API:

Fix a bug in the mmg2d API:

if the MMG2D_mmg2dmesh function was called in a loop where only the memory associated to triangles and edges was freed (MMG2D_Free_triangles, MMG2D_Free_edges functions), the library was failing with an error message about a lack of memory.

v5.1.0-beta2: This hotfix includes:

This hotfix includes:

• a bug correction in the simultaneous reduction of matrices used in the mmg2d gradation;
• the hmin/hmax truncature for anisotropic adaptation with mmg2d;
• a bug correction in the mesh saving for mmg2d (the number of edges was false);
• forgotten unscaling when the mmg2d library fails;
• a bug correction in the metric definition at ridges (anisotropic adaptation with mmg3d);
• size truncature at hmin/hmax for the internal points an the regular surface points for anisotropic adaptation with mmg3d;
• missing getters for the mmg2d API;
• a bug correction in the precision of computation in eigenv file.

It changes:

• the MMG2D_loadSol interface (remove a useless argument).
