ASTR code

Version 2.0

ASTR code is a high-order finite-difference flow solver for compressible turbulence research.

Download, Installation and Compilation

Required dependencies: Fortran 90, MPI, HDF5

Download the astr code:

git clone git@github.com:astr-code/astr.git

Compilation and installation:

ASTR 2.0 supports both gnu make and cmake. For the use of gnu make, do: make in the directory containing src folder, and the executable will be found as ./bin/astr

The cmake gives a more complete and safe way of compiling and installing the code. By default ASTR solves equations under non-dimensional form, unless the chemstry is included.

create a case folder, e.g. mkdir test_case sh path_to_the_source/script/astr.case.creater #create a new case

cmake path_to_the_source cmake --build cmake --install ctest -L nondim

The code will be installed in test_case and excutable can be found at test_case/bin/astr

If you want to use the chemstry function, you need first to install cantera. After download and unpack the cantera, you can use the following script to install: python scons/scripts/scons.py build python_package=none FORTRAN= f90_interface=y prefix= boost_inc_dir=

python scons/scripts/scons.py test

python scons/scripts/scons.py install

you may need to make and test ASTR with chemstry with following cmake commands:

cmake -DCHEMISTRY=TRUE -DCANTERA_DIR=path_to_cantera path_to_the_source

cmake --build

cmake --install

ctest -L combustion

Run the solver:

Once the excutable is built, a typical simulation can be run as, mpirun -np 8 ./astr run ./datin/input_file
