PROTO is a code that computes simple multi-frequency radiative transfer in 1D.
It uses geometrical attenuation (1/r^2) and energy-dependent opacity attenuation as exp(-tau(E)).
PROTO models the gas surrounding a protostar from the inner dust opacity gap up to the diffuse gas region following Stahler & Palla (2005; Chap. 11).
Here is the appropriate excerpt from Stahler & Palla.
PROTO is written in Fortran 95 and consists of a single class named proto (
proto_class.f90), which is called by a main program (
You can find a detailed description of the included files here, and a schematic of the data structure here.
The PROTO class contains several attributes and methods (called procedures in Fortran).
Read about how to add a new procedure to the class.
The class procedures and attributes are described here.
Some output functionality is also already implemented.
Details on the
Makefile can be found here.
