SIMMSUS source files can be downloaded here :
In order to compile the source-code you must open a Linux terminal and run the make command twice. In the first make command the compiler will produce the modules from the files variables.f90 and subroutines.f90 and the second run will use these recently created modules to produce the executable file simmsus.ex.
Since the origins of its earlier development, SIMMSUS has been tested and compiled exclusively on Linux using the Intel Fortran Compiler and up to version 2308 we have not checked if it compiles or runs using other compilers or operational systems.
In order to run a simulation, the user will need only 2 files: the executable file (simmsus.ex) and the input configuration file simconfig.dat. The user can drag these two files to a new folder to run a new set of numerical simulations defined on the configuration file simconfig.dat by typing ./simmsus.ex on the terminal. The configuration file is a text file with several questions that the user should answer in order to direct the path that SIMMSUS should cross in order to produce a specific set of simulations for the intended physics.
More information about operating SIMMSUS can be found on the trainning section of this website and on SIMMSUS manual.
