Basic use of the mmg2d library

I/ Implementation

To call the mmg2d library, you must:

1. build mesh and sol at MMG5 format;
2. call the MMG2D library;
3. get the final mesh and sol.

example0_a

We read mesh and solution files using the MMG2D_loadMesh and MMG2D_loadSol functions. Results are saved using MMG2D_saveMesh and MMG2D_saveSol functions.

example0_b

The mesh and solution are hard coded.
They are build in MMG5 format using API functions and are recovered by the same way.

We show how to recover the mesh/sol.

II/ Compilation

1. Build and install the mmg2d shared and static library. We suppose in the following that you have installed the mmg2d library in the **_$CMAKE_INSTALL_PREFIX_** directory (see the installation section of the setup guide);
2. compile the main.c file specifying:
   • the mmg2d include directory with the -I option;
   • the mmg2d library location with the -L option;
   • the mmg2d library name with the -l option;
   • with the shared library, you must add the ***_$CMAKE_INSTALL_PREFIX_** directory to your LD_LIBRARY_PATH.

‍Example 1
Command line to link the application with the mmg2d static library

gcc -I$CMAKE_INSTALL_PREFIX/include/mmg/mmg2d main.c -L$CMAKE_INSTALL_PREFIX/lib -lmmg2d -lm

‍Example 2
Command line to link the application with the mmg2d shared library:

gcc -I$CMAKE_INSTALL_PREFIX/include/mmg/mmg2d main.c -L$CMAKE_INSTALL_PREFIX/lib -lmmg2d
export LD_LIBRARY_PATH=$CMAKE_INSTALL_PREFIX/lib:$LD_LIBRARY_PATH
