How do I choose a solver when using PLECS Blockset?

Problem description: 

Simulink has 8 variable-step solvers, where do I start?

Solution: 

Unfortunately, Plexim are not experts with these either and the best source of knowledge for the Simulink solvers is really their website. However, we recommend that you start by trying the Dormand Prince (ode45) solver for non-stiff systems and either the ode15s or ode23tb solvers for stiff systems.

For a better understanding of stiffness, please refer to the solution on choosing between a stiff and non-stiff solver.
