In this article we describe how Discrete Differential Forms can be applied to spherically symmetric systems in GR. Three numerical schemes are introduced, the results of which are compared with the corresponding analytic solutions. The error of two schemes converge quadratically to zero. For one scheme the errors depend strongly on the initial data.
