COMMAND LINE PARAMETERS

AMRVAC can be invoked with command line parameters, for example:

amrvac --help

will print a welcome message:

 ---------------------------------------------------------
 ----------------- This is AMRVAC ------------------------
 ---------------------------------------------------------
 calling example:                                                
 ./amrvac -i inifile -restart 100 -convert -if datamr/data       
 default inifile is amrvac.par                            
 Note that inifile parameters overwrite the commandline        
 ---------------------------------------------------------

With the command line, it is possible to initiate a restart or convert. This has the advantage that the par file does not need to be modified. To restart a run, type

amrvac -restart 10 -if datamr/data

This will restart from the 10 output of the datamr/data file. The next output number is automatically set to 11. Note that the values assigned in the par-file will overwrite the command line parameters.

In order to initiate a convert, consider the following example

amrvac -restart 10 -if datamr/data -convert

It is trivial to default the filenameini set by -if to a meaningful filename, in which case the -if option would not need to be applied each time.

With the option -i inifile it is also possible to prescribe an alternative par-file, instead of the default amrvac.par. This comes in handy at the convert stage.

An overview of the current command line parameters is given in the following table.
