PC VERSION OF ANSOFT'S MAXWELL 3D FIELD SIMULATOR NOW PERFORMS FULL AC EDDY
CURRENT ELECTROMAGNETIC ANALYSIS

Ansoft Is First Company To Offer Computationally Intensive Eddy Current
Analysis To Windows and NT Users Designing Electrical and Electronic
Equipment

PITTSBURGH, Pa., May 10, 1994 --Ansoft Corporation, the largest provider of
electromagnetic field simulation software dedicated to the electrical
engineering market place, today announced that it has added full AC eddy
current analysis to the PC version of its Maxwell 3D Field Simulator.
Ansoft's 3D Field Simulator is the first tool to offer FEA (finite element
analysis) and full AC eddy current analysis to Windows and NT users
designing electric machinery and electronic equipment.

Keith Franz, Ansoft's vice president of sales and marketing, said of the
new capabilities, "We have always planned to support PC users with all the
capabilities available on workstation versions of our Maxwell Field
Simulators. Now for the first time, high-end 3D simulation with full AC
eddy current analysis is a reality for PC users."

Jack Parkes, Manager of Products, added, "Ansoft is the only company
offering computationally intensive eddy current analysis on a PC in the
Windows and Windows NT environment. Maxwell's Magnetic Module allows users
to simulate and account for eddy current, skin and proximity effects.
Maxwell Magnetic Solver can be used for frequencies from 60 Hz through
several hundred MHz. "

To capture the full range of eddy-current behavior, the Maxwell Field
Simulator uses a material's permittivity, permeability and conductivity
characteristics. It automatically calculates ohmic power loss and
impedance (R and L) at a specific frequency, force, torque, inductance and
stored energy using Maxwell's Electromagnetic Calculator. Other Maxwell
options include plots of flux lines, B and H fields and energy densities
over the entire phase cycle.

Ansoft's Maxwell Field Simulator is an FEA design simulation tool used by
design engineers to build sensors, transducers, relays, transformers, test
equipment, power converters, magnetic recording systems, circuit breakers,
and other electrical machinery. The simulators calculate electric
parameters such as capacitance, inductance, electrical and magnetic field
level, force, torque, current density and distributions from accurate
electromagnetic field simulations in and around electrical devices.
Ansoft's high-end interactive user interface renders the analysis and
meshing virtually transparent to users.

Ansoft's Maxwell 3D Field Simulator with 3D eddy analysis for Windows 3.1
and NT is available and priced at $28,900 US. It now includes 3D
electrostatics, DC magnetostatics, the eddy current solver and equivalent
2D solvers. Ansoft's PC version of its Maxwell 3D Field Simulator was
originally announced in September, 1993. Workstation versions of Ansoft's
3D Field Analysis start at $34,900US.

Ansoft has supplied electromagnetic tools to the design community since
1984. The company has more than 1000 customers in the United States,
Europe and Asia Pacific, with customers in the semiconductor,
communications, computer and aerospace and automotive sectors. Ansoft is
