Shape finding of cable-membrane structures has been widely discussed in the literature. A number of methods for surface shape determination have been proposed, which may be used to find the equilibrium state of the structure at specified stress levels and for prescribed boundary conditions. In recent papers the dynamic relaxation method has been used as a shape finding method. In previous papers of the present authors several strategies have been developed and considered for the parallelisation of the dynamic relaxation method. These strategies result in faster solution and shorter execution time of the design. The "speed-up" permits a second level of parallelism to appear providing the possibility for parametric studies of the design executed in parallel fashion. The introduction of parallel computing influences the whole process of the design. In this paper some of the problems that arose from the parallelisation of the design of cable-membrane structures and their solution will be presented.
