Non-linear Schrodinger Equation Solver(NLS)

Description

Package to solve non-linear Schrodinger equation written with Fortran 95 and Python 2.

NLS is scientific package that provides ability to solve effeffectively non-linear schrodinger equation with reservoir. These equation describes exciton-polariton condensation in microcavities. NLS is built on native fortran code and is based on certain natural abstraction layer that wraps native solver. These features are reason that makes calcualtions with NLS fast.

Features

core written with native Fortran
wrapped with Python interaface
[DEV] executables written with native Fortran
[DEV] support for multithreading computation
[DEV] support for distributed computation

Usage

Fortran executable

Change directory to src/
Run make
Change directory to test/
Run make and then run ./test_nls
Change directory to bin/
Run ./solve in order to start calculation
Visualize solution with python2 src/visualize.py

Python module

Change directory to src/
Run make glue in order to build python lib in bin/ directory that incapsulate native code
Use python to import native module in a way

    from nls.native import nls
    print(nls.version())

Or use python to import python wrap in a way

    from nls import Problem
    model = Problem().model()
    model.report()
    model.solve()
    model.visualize()
    model.show()

Testing

Requirements

Fortran compiler
Python libraries numpy with f2py extension, matplotlib, and scipy.
