Important for understanding the differences between the tutorials is to make clear, how the different solution types are defined. The simulation is divided into two domains. The electromagnetic domain and the thermal domain. Each of them can be defined as transient or steady state. A transient defined thermal domain means a temperature which varies over time. The steady state simulation gives the value of the converged transient temperature. Transfered to the electromagetic domain the load (current or voltage) is defined either transient or steady state. Transient means a changing load over time, steady state means the value of the settled transient load. The current can either be DC or AC.
