Verbosity levels#

When calling OOMMF different numbers of information can be shown. We demonstrate the different options for the example macrospin defined in micromagneticmodel

[1]:

import micromagneticmodel as mm

import oommfc as oc

[2]:

system = mm.examples.macrospin()

[3]:

md = oc.MinDriver()
td = oc.TimeDriver()

One summary line (default)#

The default value verbose=1 prints one summary line to the screen.

[4]:

md.drive(system)

Running OOMMF (ExeOOMMFRunner)[2023/10/18 12:41]... (0.4 s)

[5]:

td.drive(system, t=1e-9, n=10)

Running OOMMF (ExeOOMMFRunner)[2023/10/18 12:41]... (0.3 s)

Silent run#

By setting verbose=0 the calls to OOMMF do not produce any output.

[6]:

md.drive(system, verbose=0)

[7]:

td.drive(system, t=1e-9, n=10, verbose=0)

Progress bar (TimeDriver only)#

By passing verbose=2 we can get a status bar showing the progress of a running simulations. This feature is only available for the TimeDriver and solely relies on the total number of steps n and the number of files already written to disk. Therefore, the information only gives a rough indication of the progress. The progress bar is not persistent accross notebook sessions. Therefore, an additional summary line is printed at the end of the simulation.

[8]:

td.drive(system, t=100e-9, n=50, verbose=2)

Running OOMMF (ExeOOMMFRunner)[2023/10/18 12:41] took 4.1 s

When used with the MinDriver the standard one-line summary is shown instead.

[9]:

md.drive(system, verbose=2)

Running OOMMF (ExeOOMMFRunner)[2023/10/18 12:42]... (0.2 s)

[10]:

# cleanup
oc.delete(system)
