read_fortran_namelist()

read_fortran_namelist	(		file0,
			silent = True,
			b_arr = False
	)

Return a dictionary with the parameters in the namelist file (file0)
  
  @param file0 File to read from
  @param silent If false, print dictionary entries after reading
  @param b_arr Refers to an array at the bottom of the file, if one exists
  @result Dictionary containing data from file0.

			timeout = 10,
			env_vars = {}
	)

Run a shell command.

Parameters

command	Command and arguments to run
timeout	Timeout for command to complete [seconds]
env_vars	Modifications to runtime environment

Returns

result STDOUT, errcode Error code from command

write_native_mesh()

write_native_mesh	(		filename,
			r,
			lc,
			reg,
			nodesets = [],
			sidesets = [],
			ho_info = None,
			periodic_info = None
	)
