Integrated Engineering Software Inc.

Since 1984, Integrated Engineering Software has produced simulation programs for engineering and scientific design problems that involve several physical disciplines. The company describes itself as the leader in Boundary Element Method (BEM) CAE software and says it is the only supplier offering BEM, finite element (FEM) and finite difference time domain (FDTD) field solvers inside the same packages.

Why the boundary element method

According to the company, BEM gives the most accurate numerical field solutions and is the method of choice when the space around a device has to be modelled, which it calls large open regions. Its finite element solver is included alongside for problems where that approach suits better. The company pairs the technology with responsive customer service and support.

Transformers, insulators and power systems

Transformer analysis is one of the most common uses of its electromagnetic simulation software, and customers depend on the results being accurate and reliable. The company has worked with the power and distribution and manufacturing industries for decades, helping make power systems and their parts cheaper to run, more efficient and kinder to the environment. High voltage transmission is a typical example: insulators that carry power lines sit among complicated conducting structures and corona rings, and simulating a complete transmission tower with its lines is fundamental to estimating electric field levels at any point on the insulators and rings. Flashover discharges are part of that analysis.

Actuators and software development

Its actuator design programs apply the proprietary BEM technology to simulate actuators, with the FEM solver also built in. Recent releases have added a model tree for assigning physics to a model, a larger set of programming interface functions for scripting, a parametric setup dialog for analysis, new geometry creation commands and a feature for designing complex transformer windings.
