Build_adm_vol

Introduction

Purpose: Create a file that contains a 3D ADM magnetospheric structure.

Example of other programs that use a adm_vol field object: _______

The adm_vol object is defined here: Link to the class manual.

Background

The ADM model has been developed by ud-Doula et al. 2014 (add ref) and Owocki et al. 2016 (add ref).

In this implementation, the 3D grid in space is created. At each grid point, a field line is traced using the potential field object. The program determines the ADM quantities on that field line (velocity, density, temperature, etc) and records the value for the grid point considered. Then, this procedure is repeated for each grid point.

Note: This implementation of ADM was recast to work for an arbritrary magnetic topology (therefore uses the form for the ADM equations that do not explicitely use the expressions for a dipolar field line).

The only outstanding question with arbritary field lines is what would be the “top of the loop” in terms of dynamics for closed field lines. In this implementation, the top of the loop is taken to be point on the field loop with the hightest radial coordinate.

Usage

The Build_adm_vol program will create an adm_vol object.

This program creates the adm_vol object and save it to a file,
