Mesh conversion from Pointwise/Gridgen to Nektar++

In applications Pointwise (or the predecessor Gridgen) is a popular mesh generation software. In this post we go through the procedures to convert the linear mesh generated by Pointwise/Gridgen to arbitrary high order mesh for the solvers in Nektar++. The mesh conversion takes advantage of the already implemmented Gmsh interface in Nektar++. Assume we have […]

Advances in implementation of the Incompressible Navier-Stokes-Fourier solver with variable material properties

Jan Pech (Czech Academy of Sciences) Extension of the Incompressible Navier-Stokes Solver is developed for the system coupled with the energy equation. Temperature field is considered as an active quantity, which influences the flow field since the material parameters (dyn. viscosity, density, thermal conductivity) are temperature dependent. A priori, we do not simplify the problem […]

Quasi-static magneto-hydrodynamic convection in a rotating cylinder

Anthony Rouquier (Coventry University) We present a numerical study of the onset of rotating magnetoconvection in a cylinder under the quasi-static magneto-hydrodynamic approximation using the spectral-element solver Nektar++. The aim of this work is to obtain a better understanding of the convection process in planetary cores, especially in the tangent cylinder region. To this end […]
