  A numerical solution to the equations of motion for the ekpyrotic bulk brane
scenario in the moduli space approximation is presented. The visible universe
brane has positive tension, and we use a potential that goes to zero
exponentially at large distance, and also goes to zero at small distance. In
the case considered, no bulk brane, visible brane collision occurs in the
solution. This property and the general behavior of the solution is
qualitatively the same when the visible brane tension is negative, and for many
different parameter choices.
