Subroutines and functions

subroutine  implicitdiffusion/read_implicit_diff_run_pars(iomsg)
Parameters:

iomsg [character,out]

Use :

file_io (parallel_unit())

Call to:

fatal_error(), sheared_advection_fft(), transp_xy(), cyclic(), tridag(), warning()

subroutine  implicitdiffusion/write_implicit_diff_run_pars(unit)
Parameters:

unit [integer,in]

Call to:
