A transient analysis of 63.0x106 second duration is performed to simulate the two-year service life of the electrical component. The initial time step is 3.0x106 seconds. An initial normalized concentration of 1.0 and an initial temperature of 50°C are specified.
Geometric nonlinearity is activated (NLGEOM,ON), primarily to make hydrostatic pressure available during postprocessing. Loads are step-applied.
