ODE solver steps

Dear Members

 

Can I ask if there are variations in the ODE solver regarding time steps when comparing Python, Matlab, and Mathcad results side by side? I added the Matlab, Python results to the Mathcad sheet.

The outcomes for position and rotation, it seems that the steady-state results are consistent, but the response in the Mathcad file is less.

In terms of speed and rotation speed, it appears there is a disparity, suggesting that the solver may struggle to track these increments. In the attached spreadsheet, I have juxtaposed the results of Python, Mathcad, and Matlab.

Is there a way to calibrate the solver to align these graphs?

 

Thanking you in advance

Your Prime plots are almost as same as other results.

Dear ttokoro

 

Thank you for your help. Defining your domain in the ode function is important.

Everything matches
