Fig. 3From: Two-stage fourth order: temporal-spatial coupling in computational fluid dynamics (CFD)Typical wave pattern for the generalized Riemann problem. a Wave pattern for the GRP. The initial data \(\mathbf {u}(x, 0) = \mathbf {u}_{\ell } + x\mathbf {u}^{\prime }_{\ell }\) for x<0 and \(\mathbf {u}(x, 0) = \mathbf {u}_{r} + \mathbf {u}^{\prime }_{r} x\) for x>0. b Wave pattern for the associated Riemann problemBack to article page
