ANSYS EMAG

ANSYS EMAG software provides a comprehensive range of features to address the diverse simulation needs of the electromagnetics engineer. The software simulates low-frequency electric currents and electric fields in conductive and capacitive systems, and magnetic fields resulting from current sources and/or permanent magnets. It contains comprehensive simulation capabilities for static, transient and harmonic low-frequency electric and magnetic studies; permitting the simulation of steady-state current conduction, electrostatics, magnetostatics, time-harmonic quasistatic and time-transient quasistatic electric and magnetic fields. The program can also simulate charged-particle tracing in both electrostatic and magnetostatic fields. ANSYS EMAG also features a complete range of automatic calculations for force, torque, inductance, impedance, capacitance, Joule losses, field leakage, saturation and electric and magnetic field strengths.

ANSYS Emag software also includes capabilities for a circuit coupled electromagnetic analysis, which enables the user to apply harmonic, transient (including large amplitude transient) voltage and current loads directly to a finite element model via a discrete electric circuit. A variety of circuit elements are available to simulate circuit-fed devices where material saturation effects must be considered.

Combining ANSYS Emag with ANSYS Mechanical enables comprehensive multiphysics simulation of real-world phenomena including coupled thermal-electromagnetic and magneto-mechanical systems. Combining ANSYS Emag with a mechanical HPC license enables both distributed and shared memory parallel processing for low frequency electromagnetic solutions, which allows users to simulate much larger and more complex low-frequency electric and electromagnetic models.

ANSYS Emag simulates low-frequency electric currents and electric fields in conductive and capacitive systems, as well as magnetic fields resulting from currents or permanent magnets. It contains a comprehensive tool set for static, transient and harmonic low-frequency electromagnetic studies, permitting the simulation of electrostatic, magnetostatic, electromagnetic, electric circuit and current conduction. The program can also simulate charged-particle tracing in both electrostatic and magnetostatic fields. ANSYS Emag also features a complete range of automatic calculations for force, torque, inductance, impedance, capacitance, Joule losses, field leakage, saturation, and electric and magnetic field strengths.

ANSYS Emag’s circuit builder enables the user to apply harmonic, transient (including large amplitude transient) voltage and current loads directly to a finite element model via a graphically generated circuit schematic. This circuit builder permits the user to arbitrarily arrange the resistors, capacitors, diodes, inductors, wires, transformers, voltage and current sources, as well as other components. The circuit coupling to the finite element domain allows for simulating circuit-fed devices where nonlinear (saturation) effects must be considered.
