# 5.6.2.1. Central Difference¶

integrator('CentralDifference')

Create a centralDifference integrator.

1. The calculation of $$U_t + \Delta t$$, is based on using the equilibrium equation at time t. For this reason the method is called an explicit integration method.
2. If there is no rayleigh damping and the C matrix is 0, for a diagonal mass matrix a diagonal solver may and should be used.
3. For stability, $$\frac{\Delta t}{T_n} < \frac{1}{\pi}$$
