Meshfree finite differences for vector Poisson and pressure Poisson equations with electric boundary conditions

open access: yes, 2013
We demonstrate how meshfree finite difference methods can be applied to solve vector Poisson problems with electric boundary conditions. In these, the tangential velocity and the incompressibility of the vector field are prescribed at the boundary.
