WebOct 1, 2013 · If the time steps go small enough, the capacitor will dominate the I/V behavior of any finite impedance (hence, the need to use current sources with parallel resistors rather than voltage sources). Since capacitors are linear devices, the behavior becomes linear and the solver can get through the highly nonlinear behavior zones by taking them in small … Webrule, a time step of 0.1 to 1 second may be used for field cases; and smaller time step is needed for smaller scale problems. With time-accurate unsteady modeling, small time step is needed for solution accuracy purpose (not due to stability issue). • Relaxation Parameter: Next, the relaxation parameter, RELAX_H, is
