Running Multivac

Requirements

The only requirement is a C++ compiler compliant with the ANSI/ISO/IEC C++ standard (1998).

Under Linux, Multivac can be compiled by g++, the well known GNU C++ compiler. It has been successfully tested with versions 3.2, 3.3 and 3.4 of g++; but versions strictly before 3.0 are not good enough. Multivac works fine with the Intel C++ Compiler too (tested with versions 7 and 8). Under Unix, proprietary compilers should compile Multivac, even if it was not tested.

Under Windows, the last versions of Microsoft Visual C++ (from Visual C++ 2003) should compile Multivac according to its announced features, but it has not been tested.

Installing Multivac

Download the latest version of Multivac on its homepage http://spacetown.free.fr/fronts/. Expand the tarball (tar zxvf Multivac-[version].tgz), it will create a directory named Multivac-[version] ($MULTIVAC hereafter). In this directory, you will find the GNU GPL (file license), examples (files *.cpp), a makefile (makefile) and the source code itself in the directory includes.

Running Multivac

Let's compile examples provided with Multivac. In $MULTIVAC, open track.cpp which is the first example. Find the line: string Directory = "/home/vivien/Computations/Fronts/"; /home/vivien/Computations/Fronts/ is the directory where results will be stored. Change it according to your directories tree. Notice that this output directory must exist; Multivac won't create it.

Then open makefile. Most probably you don't have to modify anything. You may change the compiler. For instance, you may want to change g++ into g++-3.2 if the default compiler is g++-2.95 on your system.

Type make on the command line (still in $MULTIVAC) and it should compile successfully track.cpp.

Launch ./track from the command line. The program should terminate normally within a few seconds.

You might want to compile other examples. You can compile all of them through: make all. Before compilation, change the output directory, as for track.cpp.
