3D Modeling of Solar Oscillations with Hybridizable Discontinuous Galerkin Method
Florian Faucher, Ha Pham, Damien Fournier +5
With increasing quantity and quality of solar observations, it becomes essential to account for three-dimensional heterogeneities in wave modeling for seismic data interpretation.…
Numerical simulations of oscillations for axisymmetric solar backgrounds with differential rotation and gravity
Ha Pham, Florian Faucher, Damien Fournier +2
Local helioseismology comprises of imaging and inversion techniques employed to reconstruct the dynamic and interior of the Sun from correlations of oscillations observed on the su…
Assembling algorithm for Green's tensors and absorbing boundary conditions for Galbrun's equation in radial symmetry
Ha Pham, Florian Faucher, Damien Fournier +2
Solar oscillations can be modeled by Galbrun's equation which describes Lagrangian wave displacement in a self-gravitating stratified medium. For spherically symmetric backgrounds,…
Numerical investigation of stabilization in the Hybridizable Discontinuous Galerkin method for linear anisotropic elastic equation
Ha Pham, Florian Faucher, Hélène Barucq
This work is concerned with implementing the hybridizable discontinuous Galerkin (HDG) method to solve the linear anisotropic elastic equation in the frequency domain. First-order…
