Does the Time Step Size effects the accuracy of Results

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 … Webb30 dec. 2024 · Generally speaking, the smaller the time step, the more accurate the solution.
