A coupled thermal-electrical-stress step neglects inertia effects, and it can model steady-state or transient responses. You can use this step to simulate electrical conduction in regions of a model that use thermal-electrical-structural elements. In a steady-state, coupled, thermal-electrical-stress step, the thermal response does not depend on time. In a transient, coupled, thermal-electrical-stress step, the thermal response depends on time. Time IncrementationThe type of time incrementation determines how a coupled thermal-electrical-stress step progresses. Two types of time incrementation are available: automatic incrementation and fixed incrementation. In automatic incrementation, the solvers increment an analysis using some initial time incrementation parameters that you specify. In fixed incrementation, you specify a fixed time increment size to use throughout the analysis. CreepA coupled thermal-electrical-stress step can account for creep (that is, the viscoelastic response). The creep depends on the model's material properties. The solvers calculate creep by either implicit integration or explicit integration. |
