# Transcar 1-D time-dependent ionosphere flux tube model

![Actions Status](https://github.com/space-physics/transcar/workflows/ci_unix/badge.svg)

Python front-end, and Fortran interfacing:  Michael Hirsch

TRANSCAR 1D flux tube ionospheric energy deposition flux transport model.

Considers solar input and background conditions via MSIS, HWM.

Models disturbance propagation in ionosphere via models including LCPFCT.

## Prereqs

Because Transcar is Python & Fortran based, it runs on any PC/Mac with Linux, MacOS, Windows, etc.

Most Fortran compilers can be used, including Gfortran and Intel.

* Linux / Windows Subsystem for Linux: `apt install gfortran cmake make`

* MacOS / Homebrew: `brew install gcc cmake make`

### Windows

From native Windows

[install CMake](https://cmake.org/download)

and either of:

* [Gfortran](https://www.scivision.dev/install-msys2-windows/)

* [Intel Parallel Studio](https://www.scivision.dev/install-intel-compiler-icc-icpc-ifort/)

## Install

from Terminal / Command Prompt

```sh

git clone https://github.com/scivision/transcar

python -m pip install -e ./transcar

cmake -B transcar/build -S transcar

cmake --build transcar/build

```

## Usage

Simulations are configured in

[dir.input/DATCAR](./dir.input/DATCAR).

Simulations are run from the top directory.

Python runs Transcar in parallel using

[concurrent.futures.ThreadPoolExecutor](https://docs.python.org/3/library/concurrent.futures.html),

dynamically adapting to the number of CPU cores available:

```sh

python MonoenergeticBeams.py /tmp/tc

```

### Plotting

The simulation results are loaded and plotted by the [transcarread](https://github.com/space-physics/transcarread) Python package.
