How can I speed up the analysis in SeismoStruct, which are currently very slow?

Up until now, the development of SeismoStruct has focused primarily on the achievement of ease-of-use and high technical capabilities, with an obvious sacrifice in terms of speed of analysis, something that we hope to address in the near future. In the meantime, however, please make sure that your model does not feature an eccessive number of elements, section fibres, load increments or iterations, all of which, together with too-stringent convergence criteria, will cause the analysis to slow down quite considerably. Run sensitivity studies of similar but smaller models to find out the optimum values of the aforementioned modelling parameters that will lead to the attainment of accurate results but at a lower computational cost, before embarking on time-consuming analyses of very large models. Please recall also that if you are, for instance, interested in predicting the top displacement of a building (i.e. global response) subjected to monotonic loading, you are most likely not to require the same level of mesh/fibre refinement that you would need if trying to predict the failure strain of a column section (local response) subjected to cyclic loading.
