Simulink has 8 variable-step solvers, where do I start?
What is stiffness and the difference between the two types of solvers?
My simulation stopped suddenly with this message, but it had been running fine up until then, why does this happen?
I want to run a new simulation using a previous system state, for example to get past start-up transients in my system. Is this possible?
Both settings appear to reduce the time between simulation steps and provide more accurate output, but is there a reason for using one over the other?
I notice that the output in the scope appears more or less correct but the curve is jagged and not smooth. I can reduce the step size or tolerances and the output becomes more smooth, but this is at a cost of simulation speed. Is there a better solution?
I have tried multiple settings and the waveforms before the error occurs look good. What is the reason for this error and is there anything I can do about it?
I have controls running at a fixed-step, but I want to be able to simulate the electrical phenomena of the plant with variable-step since this is faster and more efficient. Is there a solution for a hybrid time step?
My simulation appears to be running very slowly. How can I accelerate it?
In Simulink, I have the choice between various variable-step solvers. Which is best to use with PLECS?
