“…Multiwavelets (MW) are directly compatible with the piecewise-polynomial bases of FV and DG solvers and provide a multiresolution analysis that enables a dynamically adaptive solution that overcomes known shortcomings of conventional adaptive mesh refinement methods (Dahmen, 1997;Cohen et al, 2001;Müller, 2003;Lamby et al, 2005;Díaz Calle et al, 2005;Smith et al, 2008;Dahmen et al, 2010;Archibald et al, 2011;Hovhannisyan et al, 2013;Haleem et al, 2015;Kesserwani et al, 2015;Gerhard et al, 2015b;Gerhard and Müller, 2016;Guo and Cheng, 2016;Wang et al, 2016;Sharifian et al, 2019;Tao et al, 2019). Kesserwani et al (2019) adopted multiwavelets and Haar wavelets to formulate adaptive one-dimensional (1D) MWDG2 and HFV1 hydrodynamic solvers, and found that the 1D-MWDG2 solver achieved the accuracy of the uniform DG2 solver for a runtime cost less than the uniform FV1 solver.…”
