Nonlinear solver fail to converge due to Linear Algebra error. Failed to solve using iteration matrix

Hello, I am trying to build an electric vehicle model. This includes a drive cycle, Longitudional driver, PWM control blocks, DC motor, transmission and a vehicle body. The solver configuration fails to work no matter what, I have tried several combinations, also removed some blocks to check if the error goes away.

Ok. So apparently you are doing something wrong. Can we know what? The crystal ball is sooooo foggy these days. It just refuses to let anyone see inside your computer.

I can try reading some tea leaves, if you think it might work.

Hi, well what can I say. I am doing something wrong. I wish I knew what it was, then I would not ask for help. Tea leaves is a great idea, if you can see whats wrong with that then do let me know.

Without a model we cannot point to any root cause because there are many aspects that can cause this. Can be for example a modeling issue, model parameterization, or a combination of the two.
