In this companion paper to [J. Chan, R. J. Hewett, and T. Warburton, Weight-adjusted discontinuous Galerkin methods: wave propagation in heterogeneous media, preprint, https:\/\/arxiv.org\/abs\/1608.01944, 2016], we propose weight-adjusted DG (WADG) methods for curvilinear meshes which reduce storage costs while retaining energy stability. A priori error estimates show that high order accuracy is preserved under sufficient conditions on the mesh, which are illustrated through convergence tests with different sequences of meshes. Numerical and computational experiments verify the accuracy and performance of WADG for a model problem on curved domains.<\/jats:p>","DOI":"10.1137\/16m1089198","type":"journal-article","created":{"date-parts":[[2017,11,2]],"date-time":"2017-11-02T11:02:14Z","timestamp":1509620534000},"page":"A2395-A2421","source":"Crossref","is-referenced-by-count":27,"title":["Weight-Adjusted Discontinuous Galerkin Methods: Curvilinear Meshes"],"prefix":"10.1137","volume":"39","author":[{"given":"Jesse","family":"Chan","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Russell J.","family":"Hewett","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"T.","family":"Warburton","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"351","published-online":{"date-parts":[[2017,11,2]]},"reference":[{"key":"atypb1","doi-asserted-by":"publisher","DOI":"10.1016\/j.cma.2011.08.019"},{"key":"atypb2","doi-asserted-by":"publisher","DOI":"10.1090\/S0025-5718-02-01439-4"},{"key":"atypb3","doi-asserted-by":"publisher","DOI":"10.1007\/s10915-009-9334-9"},{"key":"atypb4","doi-asserted-by":"publisher","DOI":"10.1002\/num.21703"},{"key":"atypb5","doi-asserted-by":"publisher","DOI":"10.1007\/s10915-011-9566-3"},{"key":"atypb6","doi-asserted-by":"publisher","DOI":"10.1007\/978-3-642-84108-8"},{"key":"atypb7","unstructured":"M.
