The simulation speed depends on the used hardware and the solver obviously. The simulation of a Batemo Cell in MATLAB Simulink R2016b with a fixed-step solver at a step size of 100ms is about 100x faster than real time on a normal office notebook (Lenovo ThinkPad L460). In practice, this means that typical simulations just take a couple of seconds.
When a powerful workstation simulates the Batemo Cell, the simulations are typically 200x to 300x faster than real time.
