Obtaining Nmesh

git clone https://github.com/nmeshsource/nmesh.git

Copy the file MyConfig into the newly created nmesh directory.

Type:

cd nmesh
make git_clone

Compiling Nmesh

To compile you need a file called MyConfig. In it you need to set a few things like the compiler you use or where certain libraries are located. The file linked here is an example that works on Debian. Among other things it has the section:

#SPECIALLIBS += -lgsl -lgslcblas  # for GSL

This line is currently commented out, but any SPECIALLIBS lines simply describe what libraries we want to compile in. Of course this only works if they are actually installed. See Compile Notes for more details about compiling and MyConfig variables such as SPECIALLIBS. Read the Library Notes to find out more about compiling on supercomputers such as FAU's Athene.

Parameter files for Nmesh

Several example parfiles are in nmesh/src/tests/scalarwave1/parfiles , with descriptions in nmesh/src/tests/scalarwave1/parfiles/Note.txt .

Running Nmesh

Nmesh can use MPI, so you can compile and run with mpicc and mpirun. On Athene, Nmesh and also BAM or Sgrid can also be started with the submitjob script found at https://github.com/wofti/WTscripts. For slurm you also need slurm_mpirun_script.

Developer access to main part of Nmesh

To be able to push to the Nmesh source code repo, access it via:

git clone git@github.com:nmeshsource/nmesh.git

About the non-public git repos of the FAU NR group

Some Nmesh projects that are still under development reside in the non-public FAU NR git repos.
