depSolver depSolver

depSolver is a Boundary Element Method solver for Laplace's equation in 3D AC electrostatic problems. It handles multiple materials and Dirichlet boundary conditions. The discretization is done using isoparametric triangles, and both linear and quadratic elements are available.

Description


depSolver is a Boundary Element Method solver for Laplace's equation in 3D AC electrostatic problems. It handles multiple materials and Dirichlet boundary conditions. The discretization is done using isoparametric triangles, and both linear and quadratic elements are available. The user can choose between an iterative GMRES solver with Jacobi preconditioner and a Gauss elimination solver with backsubstitution and partial pivoting. depSolver was originally written to study the characteristics of different dielectrophoretic trap designs, but it can be used to solve a wide variety of electrostatic problems. The source code is written in C and uses separate functions for most tasks in order to make modifications easier. Please refer to the user guide for detailed information.

Electric field intensity in the plane z = 17.5 micrometers for a dielectrophoretic trap that consists of two sets of four circular electrodes with alternating potentials (trap height is 50 micrometers). The peak breaking the symmetry of the field is due to the presence of an insulating particle.
