This paper describes the implementation of an ANSYS Parametric Design Language (APDL) macro called CAMACO for the computation of capacitance matrixes of arbitrarily shaped 3D objects in arbitrarily distributed dielectrics via the conservation of field energies. APDL as the interface language of the general purpose FEM system ANSYS-Multiphysics™ provides an(More)
The study of microsystems containing photonic crystals (PC) and meta-materials are rapidly growing fields of research. Finite-Difference Time-Domain (FDTD) full wave electromagnetic solvers are now increasingly used to investigate and design such systems. However, in order to simulate the electromagnetic response of such complex systems containing a large(More)
A fundamental problem of all FEM capacitance computations in MEMS and ULSI is to determine proper mesh size for the elements representing the considered model. In particular, optimal mesh size selection is crucial for large 3D models to limit the required computational effort. However, automatic mesh refining algorithms are not applicable and/or desirable(More)
