Contribution of dissipative structures and their different natures to global dissipation. Top plots: fraction of the total dissipation high dissipation structure contribute to (black line) and the contribution of cells that belong to a scan that is identified (coloured areas) for OT and ABC initial conditions simulations. Bottom plots: we use the most represented identification in each structure and attribute the total dissipation rate of the structure to this kind. This method is supported by the fact that we find connected structures to be mainly made of one kind of discontinuity.
