Simulation progress does not rise from 20%.

Simulation progress doesn't go up at 20%. It's always at 20% no matter how many times I repeat it.

In order to find the precise cause and solution for the issue you are currently experiencing, I believe that the following additional information would be necessary. If you could provide the following information, it would enable contributors, including myself, to assist you more effectively:

1) Detailed description of the issue

- Precise information on MATLAB Release and OS would be also helpful. You can find this with the command "ver". (You can obfuscate your license number.)

2) Example files and data files that can reproduce the issue

3) Exact steps to reproduce the same problem using the files you provided

4) All error messages that appear when the issue occurs

Hi @상원 안

In my experience, the system's dynamics probably become extremely stiff as the simulation progresses towards 20%. Use ode15s; otherwise, consider ode23s if you find ode15s inefficient.
