MOCASSIN 2.02 manual

Pure dust benchmarks

Version 2.0 was designed for the modelling of regions where dust grains and photoionised gas coexist in the same volume; however extreme care has been taken so that the code could also be run efficiently when only one or the other process is included. In this section we will see briefly how to run dust-only models by attempting to reproduce pure dust 1D and 2D models as shown by Ercolano, Barlow and Storey (2005, MNRAS, 362, 1038).

1D Benchmarks

A set of spherically symmetric benchmark models and solutions are described by Ivezic et al. (1997, MNRAS, 291, 121). The input files used by MOCASSIN for some of these benchmarks are included in the directory ~/mocassin.X.XX/benchmarks/dust/1D.

Copy the input file of the benchmark you wish to run into the mocassin.X.XX/input subdirectory and rename it input.in or link the input.in file to the benchmark file. Then run the code (see pure photoionisation benchmarks) and finally compare the output files (SED.out, dustGrid.out, see output files) with the results published by Ercolano, Barlow and Storey (2005, MNRAS, 362, 1038)

2D Benchmarks

A set of 2D disk benchmark models and solutions are described by Pascucci et al. (2004, A&A, 417, 793). Sample input files used by MOCASSIN for some of these benchmarks are included in the directory /usr/share/mocassin/benchmarks/dust/2D.

As for the 1D benchmarks you will have to copy the input files of the benchmark you wish to run into the mocassin.X.XX/input subdirectory and rename it input.in or link the input.in file to the benchmark file. Then run the code and finally compare the output files (SED.out dustGrid.out, see output files) with the results published by Ercolano, Barlow and Storey (2005, MNRAS, 362, 1038).
