MOCASSIN 2.02 manual
Compile mocassin, mocassinWarm, mocassinOutput or mocassinPlot
In the tar ball you should find an example makefile; this was coded for use with the current free Intel F90 compiler (ifort 8.0.034) and the standard free MPI libraries (mpich-1.2.5.2) Please edit the make-file to suit the path of the compiler and mpi libraries on your system. Some compilers may require different/additional optimisation flags.
Several other makefiles created for a number of different platforms are also included (e.g. makefile.sun etc..); these are only given as further examples and are not being mantained. Whatever you do PLEASE be careful with aggressive optimization switches. -O5 seems to work fine on all platforms so far, but -fsimple=2 gives serious problems.
ALWAYS RUN A BENCHMARK CASE WHEN COMPILING ON A NEW PLATFORM!!.
There are four drivers for MOCASSIN:
mocassin: the main MOCASSIN driver that is used to start a new simulation.mocassinWarm: the driver that is used to resume an interrupted simulation.mocassinOutput: runs the output routines using the current grid files in the output subdiretory.mocassinPlot: uses the current grid files in theoutput/subdirectory to create 3d-emission maps.
To compile either of these drivers you need to do type:
make mocassin
make mocassinWarm
make mocassinOutput
make mocassinPlot
WARNING!!!! Sometimes (e.g. on the SUN) the makefile is such that you have to type make first, this will make all the object files, then to link up one of the versions of the driver listed above type
make mocassin
make mocassinWarm
make mocassinOutput
make mocassinPlot
.... if no compiler errors and everything has gone smoothly then the sun will shine and all will be very nice.. if you get compilation errors please email them to me and I will try to help if I can.
IMORTANT NOTE: If you are using an IBM platform and the makefile provided here then you will also need to change all the module file extensions from .f90 to .f (this is because for some annoying reason the compiler only looks for .f files.. I am sure there must be a way around this, but I couldn’t find it, if you do, please let me know!). The file extensions can be easily changed using the following command:
rename 's/f90$/f/g' *f90
