Using the boundary element method (BEM) and Lagrangian crack-fronts, we produce highly detailed fracture surfaces. The computational cost of the BEM is alleviated by using a low-resolution mesh and interpolating the resulting stress intensity factors when propagating the high-resolution crack-front.\r\n\r\nOur system produces physics-based fracture surfaces with high spatial and temporal resolution, taking spatial variation of material toughness and/or strength into account. It also allows for crack initiation to be handled separately from crack propagation, which is not only more reasonable from a physics perspective, but can also be used to control the simulation.\r\n\r\nSeparating the resolution of the crack-front from the resolution of the computational mesh increases the efficiency and therefore the amount of visual detail on the resulting fracture surfaces. The BEM also allows us to re-use previously computed blocks of the system matrix.","lang":"eng"}],"intvolume":"        34","publist_id":"5522","volume":34,"year":"2015","file_date_updated":"2020-07-14T12:45:07Z","ddc":["000"],"project":[{"call_identifier":"H2020","grant_number":"638176","_id":"2533E772-B435-11E9-9278-68D0E5697425","name":"Efficient Simulation of Natural Phenomena at Extremely Large Scales"}],"doi":"10.1145/2766896","has_accepted_license":"1","author":[{"first_name":"David","last_name":"Hahn","full_name":"Hahn, David","id":"357A6A66-F248-11E8-B48F-1D18A9856A87"},{"orcid":"0000-0001-6646-5546","first_name":"Christopher J","last_name":"Wojtan","id":"3C61F1D2-F248-11E8-B48F-1D18A9856A87","full_name":"Wojtan, Christopher J"}],"ec_funded":1,"citation":{"ieee":"D.
