Sample Scripts for Running Test Problems

• contrib/astro/testsuite/subst.s - Changes values of variables in namelist type formatted files.
  • Example:

     subst.s iDivB 3 physics.data
    

    will set iDivB to 3 in the physics.data file
  • For array data, there can be no white space between values. If your data file has an entry like

    qTolerance    =   1e-3 1e-3 1e-3 1e-3 1e-3
    

    and you call

    subst.s qTolerance 1e-2 1e-2 1e-2 1e-2 domain.data
    

    you will get an error message because there are two many arguments. If instead you call

    subst.s qTolerance 1e-2,1e-2,1e-2,1e-2 domain.data
    

    then it will modify qTolerance in domain.data but only the first entry

    qTolerance    =   1e-2,1e-2,1e-2,1e-2 1e-3 1e-3 1e-3 1e-3
    

    The solution is to remove white space in array lists in your data files that you want to swap.

    qTolerance    =   1e-3,1e-3,1e-3,1e-3,1e-3
