ebtelplusplus

ebtelplusplus is an implementation of the enthalpy-based thermal evolution of loops (EBTEL) model for doing efficient hydrodynamics of dynamically-heated solar coronal loops. ebtelplusplus decouples the electron and ion energy equations such that the two populations can evolve separately. This implementation also includes effects to due to cross-sectional area expansion.

If you are looking for the original EBTEL implementation, the you can find the repository for the IDL code here.

Installation

The easiest way to install ebtelplusplus is through pip,

pip install ebtelplusplus

If you would like to compile and build the package from source, see the instructions here.

Usage

The code snippet below shows how to set up a simulation for a 40 Mm loop, lasting 2 hours, heated by a single heating event lasting 200 s in which all of the energy is injected into the electrons,

import astropy.units as u
import ebtelplusplus
from ebtelplusplus.models import HeatingModel, TriangularHeatingEvent

heating = HeatingModel(
    background=1e-6*u.Unit('erg cm-3 s-1'),
    partition=1,
    events=[TriangularHeatingEvent(0*u.s, 200*u.s, 0.1*u.Unit('erg cm-3 s-1'))]
)
results = ebtelplusplus.run(2*u.h, 40*u.Mm, heating)
