NEWS (2008-11-10) Bugfix release 2.1 available for download in patch and full version forms. It fixes a mistake in the multipolar calculation of orders 2 and 3 for quadratic triangular elements. All previous versions have been marked as Deprecated to avoid confusion, but they are still available for ... [More] download for those who need them for development purposes (go to downloads and select "All Downloads" then click "Search"). DescriptiondepSolver is a Boundary Element Method solver for Laplace's equation in 3D AC electrostatic problems. I originally wrote this program to study the characteristics of different dielectrophoretic trap designs. A big advantage of using this code to calculate dielectrophoretic forces is that the user can specify which approximation to use for the calculation of the force. In this manner, without having to change anything in the code, one can use a simple dipolar or quadrupolar approximation to quickly explore the force generated on a sphere over a large volume of space, or use the more general calculation based on the integration of the Maxwell's stress tensor over an arbitrarily shaped particle. depSolver is convenient for dielectrophoretic force calculations, but it is in no way limited to them. It can be used to solve a wide variety of electrostatic problems as long as they involve conductors were the electric potential is specified and all dielectrics in the system can be considered as piecewise homogeneous. The source code is written in C and uses separate functions for most tasks in order to make modifications easier. [Less]

stksolver

stkSolver is a boundary element method solver for Stokes' equation in microfluidics problems. Version 1.0 supports only a single material and Dirichlet boundary conditions (given velocity). The discretization is done using isoparametric triangles, and both linear and quadratic elements are ... [More] available. An indirect version of BEM is used in order to obtain equations which are numerically stable. [Less]
