Installation

Installing LaMEM can simply be done through the package manager:

julia>]
pkg>add LaMEM

which will download the binaries along with PETSc and mpiexec for your system.

You can test if it works on your machine with

pkg> test LaMEM

Running LaMEM from the julia REPL

Running LaMEM from within julia can be done with the run_lamem function:

LaMEM.Run.run_lamem — Function

run_lamem(model::Model, cores::Int64=1, args:String=""; wait=true)

Performs a LaMEM run for the parameters that are specified in model

source

run_lamem(ParamFile::String, cores::Int64=1, args:String=""; wait=true, deactivate_multithreads=true)

This starts a LaMEM simulation, for using the parameter file ParamFile on cores number of cores. Optional additional command-line parameters can be specified with args.

Example:

You can call LaMEM with:

julia> using LaMEM
julia> ParamFile="../../input_models/BuildInSetups/FallingBlock_Multigrid.dat";
julia> run_lamem(ParamFile)

Do the same on 2 cores with a command-line argument as:

julia> ParamFile="../../input_models/BuildInSetups/FallingBlock_Multigrid.dat";
julia> run_lamem(ParamFile, 2, "-nstep_max = 1")

source

Running LaMEM from outside julia

If you, for some reason, do not want to run LaMEM through julia but instead directly from the terminal or powershell, you will have to add the required dynamic libraries and executables. Do this with:

LaMEM.Run.show_paths_LaMEM — Function

show_paths_LaMEM()

The downloaded LaMEM binaries can also be called from outside julia (directly from the terminal). In that case, you will need to set load correct dynamic libraries (such as PETSc) and call the correct binaries.

This function shows this for your system.
