We develop an a-posteriori error indicator which depends on the norm of a local residual operator. WebMar 11, 2024 · The GMsFEM, a systematic approach, constructs multiscale basis functions via local spectral decomposition in pre-computed snapshot spaces. We show that GMsFEM can automatically identify separate fracture networks via local spectral problems. We discuss the relation between these basis functions and continuums in multi-continuum … pink bike cable housing
