Efficient and well-conditioned ghost-point discretization of boundary operators on unfitted domains
Armando Coco, Alessandro Coclite, Stéphane Clain +1
Unfitted boundary methods are widely used to numerically solve partial differential equations (PDEs) on irregular domains, avoiding the computational burden of generating boundary-…

High order ghost-FEM for incompressible Navier-Stokes equations on moving domains
Hridya Dilip, Clarissa Astuto, Armando Coco +1
We develop a new numerical technique for approximating solutions of the Navier-Stokes equations on moving domains. The method aims at simulating an incompressible fluid past an obj…
