Nature of problem:
Dynamics of two co-dimension one branes in a five-dimensional spacetime with a bulk scalar field and arbitrary potentials. The dynamics is governed by the five-dimensional Einstein equations of gravity and the junction conditions at the position of the branes.

Solution method:
Leapfrog Algorithm to solve system of (1+1)-dimensional partial differential equations; Initial & boundary value problem

Restrictions:
Assumption of homogeneity along three spatial dimensions parallel to the branes.

Running time:
Depending on the grid size and length of the time evolution: from ~ 1 sec to ~ 1 hours or longer
