The generation of a start file and the modification of the parameter file is a somewhat complex process. In short, the following steps have to be performed.
rhd.exe(see Sect. 3.1) and put it into your working directory.
rhd.par: typically, you will start with an existing file and edit it. You should check that the paths and names of EOS, opacity, and start file are set correctly (Watch the username!). For details about the parameter file see Sect. 5.3.1.
nice nohup rhd.exe > rhd.out &
tail -f rhd.out
rhd.par). Their contents can be read and analyzed with IDL routines (see Sect. 4.7.3).
For machines with batch queue (CRAYs in Kiel, SUN1 in Uppsala) there is the script (originally) from Hans-Günter Ludwig, which can handle an entire sequence of simulations.
