Numerical and analogue models are often used to investigate the evolution of deformation processes at various scales in crust and lithosphere. In both approaches, the freedom in choice of simulation method, materials and their properties, and deformation laws could affect model outcomes. To assess the role of modelling method and to quantify the variability among models, we have initiated a comparison of three brittle wedge experiments run by 15 analogue laboratories and 11 numerical codes. In this splinter meeting we will present results of the comparison experiments, with the aim to have an open discussion on the achievements so far.
