Micro Abstract:
The level set formulation, in contrast to a laminate approach, provides more information considering domain wall kinetics in ferroelectrics since the microstructure is simulated with a spatial resolution. The level set function is defined as a signed distance function to the domain wall. In the variational approach, an internal energy penalises the deviation from the signed distance function due to numerical errors which is computationally more efficient than the commonly used reinitialization.
