Take a look to the TwoDomain() command. There are examples on the
example page under Initial Magnetization, and the API explains in more detail. You can give commands such as 'm = TwoDomain(1,0,0, 0,1,0, -1,0,0)' for a Neel wall, or 'm = TwoDomain(1,0,0, 0,0,1 , -1,0,0)' for a Bloch wall. The command inputs are the left domain magnetization, the orientation of the wall, and then the right domain.
You can of course transform them using transformation commands similar to shapes, such as rotations, translations etc. By default they start at the center of your geometry
