2.2.4. Concurrent Multi-scale Modelling Within the numerical simulation procedure, such thing as multi-scale modelling is used to please the computational time while maintaining the result’s accuracy. Multi-scale modelling is one of several ways in approaching engineering problems related to fractures and failures of structural components. Computationally, to be able to e ffi ciently maximise its capability, it is highly beneficial to perform the multi-scale analysis. Regions that are prone to fracture are modelled in a more detailed and refined elements compared to other fields. On the regions far away from the fine scaled model, a less expensive coarse scale model is used to capture the far field behaviour with lower spatio-temporal resolution
