Nettet4. mai 2024 · This is an urgent stuation. I got a proble to get the value of instantaneous step size value in variable step solver. In my simscape model there is also a runge kutta solver function that I wrote and I need a h value which is a h=step_value/10. I dont want to use fixed step solver. That is why I need to know step value for each time step. Nettet10. apr. 2024 · 0. When I run scipy.solve_ivp with LSODA or scipy.odeint, I set an rtol and atol as well as min_step. The desired behavior is to try to reach the fixed atol/rtol, but only let the step size go so small for memory and computation purposes. If it does not reach the tolerance with h=hmin, the integration should continue, perhaps with a warning.

NettetThe step size in the Simulink fixed solver is 1e-06, but I need a pulse width of 2e-08. The figure shows the clear requirement of the required pulse. The problem I am facing is that the computed sample time of the pulse is not an integer multiple of the step size. I am looking for an alternative idea for creating the pulse in fixed point solver. Nettet24. mai 2024 · The Fixed-step size is the time interval after which the solver solves a Simulink model. Hence, all the sample times in a Simulink model must be an integer multiple of the fixed-step size. In your example, the fixed-step size is 10000000 (e7).
