A priori error estimates of a diffusion equation with Ventcel boundary conditions on curved meshes
Fabien Caubet, Joyce Ghantous, Charles Pierre
In this work is considered an elliptic problem, referred to as the Ventcel problem, involvinga second order term on the domain boundary (the Laplace-Beltrami operator). A variation…

Finite element analysis of a spectral problem on curved meshes occurring in diffusion with high order boundary conditions
Fabien Caubet, Joyce Ghantous, Charles Pierre
In this work is considered a spectral problem, involving a second order term on the domain boundary: the Laplace-Beltrami operator. A variational formulation is presented, leading…
