Detailed Description

Basic use of the mmg2d library to perform mesh adaptation with 2 calls of the library and deletion of the metric between the call.

I/ Implementation

This example:

1. build mesh and metric at MMG5 format;
2. call the MMG2D library;
3. get the mesh and metric and save its;
4. remove the metric to not reuse it;
5. call again the MMG2D library;

1. get the final mesh.

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

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
