This paper presents an implementation of a parallel environment for the solution of large non-conventional finite element systems. A topological data structure is used to define the finite element discretisation. The procedures previously developed for sequential processing are used to compute the coefficients of the matrices involved. Alternative variants of the CG algorithm for the solution of the linear system are tested and compared.
