Nektar++: Design and implementation of an implicit, spectral/ element, compressible flow solver using a Jacobian-free Newton Krylov approach
Zhen-Guo Yan, Yu Pan, Giacomo Castiglioni +4
At high Reynolds numbers, the use of explicit in time compressible flow simulations with spectral/ element discretization can become significantly limited by time step. To alle…
Naturally curved quadrilateral mesh generation using an adaptive spectral element solver
Julian Marcon, David A. Kopriva, Spencer J. Sherwin +1
We describe an adaptive version of a method for generating valid naturally curved quadrilateral meshes. The method uses a guiding field, derived from the concept of a cross field,…
-adaptation for compressible flows
Julian Marcon, Giacomo Castiglioni, David Moxey +2
We present an -adaptation strategy for high-fidelity simulation of compressible inviscid flows with shocks. The mesh resolution in regions of flow discontinuities is increased…
Numerical study on the effect of geometric approximation error in the numerical solution of PDEs using a high-order curvilinear mesh
Sehun Chun, Julian Marcon, Joaquim Peiro +1
When time-dependent partial differential equations (PDEs) are solved numerically in a domain with curved boundary or on a curved surface, mesh error and geometric approximation err…
Nektar++: enhancing the capability and application of high-fidelity spectral/ element methods
David Moxey, Chris D. Cantwell, Yan Bao +14
Nektar++ is an open-source framework that provides a flexible, high-performance and scalable platform for the development of solvers for partial differential equations using the hi…
A semi-structured approach to curvilinear mesh generation around streamlined bodies
Julian Marcon, Joaquim Peiró, David Moxey +3
We present an approach for robust high-order mesh generation specially tailored to streamlined bodies. The method is based on a semi-sructured approach which combines the high qual…
