I want to see the graph of domain wall velocity vs field extent and current extent applied in OOMMF. Is there any way to manage so that we could obtain such graphs from OOMMF? So far I am getting the magnetization texture as output and can also get the data for the texture in the text file.
I think domain velocity is approximately given by L/2*dMx/dt. But there might be better and easier way to calculate from OOMMF.
And what about the domain wall position? How is it calculated with varying time in OOMMF?
For that approximation, the domain wall position might be given by:
x(t) = (L/2)*[+1]
v(t) = dx(t)/dt = (L/2)*d/dt

There were some related messages in the old oommf mailing list archive (which no longer exists). I will resend them to the oommf mailing list in a single message with the subject "How to calculate the domain wall motion velocity?" so that they should appear in the new oommf mailing list archive that you can find a link to at
http://www.ctcms.nist.gov/~rdm/email-list.html
However, I don't know when the next archive update will occur (i.e., how long it will take for it to appear in the archive).
