The magnetization should first relax before running, no?

And the domain wall tends to move fully to the side if placed too close to a boundary :/

The system should relax before setting the strain (since at t = 0s the strain is non-zero). This should not take long...

Perhaps use "squash and merge" for this branch instead of simply merging. |

This example is based on the simulation and experiment they did in Mechanism to transfer linear momentum from a Surface Acoustic Wave to a Magnetic Domain Wall.
Its a ferromagnet with a domain wall and by applying a time and space dependent strain (representing a SAW) coming from the right, the wall moves towards the left.
The example shows the initial and final magnetization and also shows a plot of the DW position (estimated by a linear interpolation using the average magnetization) in function of time.
