Nonlinear Systems, Inc. conducts computational research with an emphasis on systems with coupled fields and nonlinear material properties such as electric and thermal field-dependent conductivity, dielectric constant, and/or thermal properties. Nonlinear Systems has developed proprietary software for solution of such systems. Applications include metal oxide varistors, lightning arresters, nonlinear field grading elements, capacitor dielectrics which include nonlinear fillers, end turn grading of rotating machines, etc.
Nonlinear Systems, Inc. can also compute dielectric spectra from FEA models of physical systems and can characterize nonlinear dielectrics over a wide range of conditions.
