The 3 steps to run RASCAS

RASCAS works in three steps. First, one creates a set of mesh/domain files with CreateDomDump. Second, one creates initial conditions for photons, with PhotonsFromStars. Finally, one runs the radiative transfer with rascas. Each code has its parameter file. We will discuss in more details each of these steps below:

• Creating a set of the mesh/domain files with CreatDomDump

• Generating the Photon Packet Initial Condition (PPIC) file with one of the three PPIC codes

• Running the radiative transfer
