Step size for fixed-step solver - MATLAB - MathWorks

WebFor Sine and Signal Generator source blocks, if the stop time is Inf , Simulink calculates the step size using this heuristic: h max = min ( ( 0.2), ( 1 3) ( 1 F r e q max)) Otherwise, the step size is: h max = min ( t s t o p − t s t a r t 50, ( 1 3) ( 1 F r e q max)) where F r e q max is the maximum frequency (Hz) of these blocks in the model. WebWhen the stop time is inf or is equal to the start time, the maximum step size is 0.2. For all other stop time values, the maximum step size is chosen such that the simulation has at least 50 time hits. h max = t s t o p − t s t a r t 50. When your model includes a Sine Wave block or a Signal Generator block, the maximum step size is ... WebSolution: The maximum step size simply limits the solver to a specified largest possible time step. It can be used if you suspect that the solver is missing events, however this setting does not influence the accuracy of the output. high times calendar 2023
