  In this article we describe applications of Discrete Differential Forms in
computational GR. In particular we consider the initial value problem in vacuum
space-times that are spherically symmetric. The motivation to investigate this
method is mainly its manifest coordinate independence. Three numerical schemes
are introduced, the results of which are compared with the corresponding
analytic solutions. The error of two schemes converges quadratically to zero.
For one scheme the errors depend strongly on the initial data.
