-FEM: an efficient simulation tool using simple meshes for problems in structure mechanics and heat transfer
Stephane Cotin, Michel Duprez, Vanessa Lleras +2
One of the major issues in the computational mechanics is to take into account the geometrical complexity. To overcome this difficulty and to avoid the expensive mesh generation, g…

A new -FEM approach for problems with natural boundary conditions
Michel Duprez, Vanessa Lleras, Alexei Lozinski
We present a new finite element method, called -FEM, to solve numerically elliptic partial differential equations with natural (Neumann or Robin) boundary conditions using simpl…
