This is a document for DelFEM library. DelFEM : http://code.google.com/p/delfem/ DelFEM is a library, which try to provide a handy environment for creating Finite Element Method (FEM) programs. *Build DelFEM is written in C++, so probably you can compile it with many different C++ compilers. But I recommend you to use gcc with which I usually compile the library. GLUT system is also an requirement to build the library. **Windows To use gcc in windows, you can use MinGW. MinGW : http://www.mingw.org/ For the GLUT system, please install freeGLUT for MinGW. Free GLUT: http://freeglut.sourceforge.net/ Please build the library by execute command "make" for the library Makefile at "DelFEM/Makefile". The make command of MinGW is "mingw32-make". **Linux Please build the library by execute command "make" for the library Makefile at "DelFEM/Makefile". **Mac You can either make this system with "make" command or using Mac XCode system. The XCode project file for building DelFEM library is in "DelFEM/lib/xcodelib_core/" *Examples Example projects are placed in (DelFEM/test_glut/). Since there is no detailed manual for this library, I recommend to learn the usage from the examples. ---- Please enjoy!!
