Before now, all the problems that have been addressed were steady. In other words neither the primary variable nor the flux had any time history. Steady state solutions may be viewed as states of equilibrium which only become altered when the dynamic forces ensuring equilibrium are altered. With this understanding it means that transient problems could be considered as going through quasi-steady states. Although steady state solutions have their value, especially in evaluating the performance of a system under equilibrium conditions, the real world is dynamic in nature. States of equilibrium are rarely maintained for too long, so that the time history of the performance of the system has to be closely monitored in order to capture its complete picture.
