Webb14 mars 2010 · If you don't specify a maximum timestep (TMAX), Multisim will automatically choose a TMAX based on the length of your transient simulation (TSTOP). In the event that Multisim can't solve for the next time step, it will choose a smaller timestep. It will keep trying smaller timesteps until it reaches some fraction of TMAX before giving … Webb16 mars 2024 · With the Times list for the Time-dependent solver set to range(0,0.1,10) and the default solver settings (Fully Coupled, Constant (Newton), Direct, and Minimal Jacobian update) and a sinusoidal coil excitation of 10 A, we find that the solution spanning 5 periods (end time 10 s) is achieved in about 100 time steps.It is important to …
