The program cppsimu is used to simulate radiative transfer of line emission in molecular clouds. The program can be obtained from the author. The versions available on the web contains the following limitations:

  • only one-dimensional (spherically symmetric) and three-dimension (cartesian grid) geometries
  • no handling of overlapping lines
  • no calculation of cooling efficiencies or thermal balance

These manual pages should be more up to date and may refer to some options not available in the publicly available version of the program.

Before running the program one must set up a parameter file and provide files containing molecular data and collision coefficients. It is better to keep all these files in the current working directory (at the moment a separate directory for molecular data etc. can be specified only at compile time). The following links contain detailed information about the input and output files and their formats.
