EMA3D® Charge Official Release

Electro Magnetic Applications, Inc. and Ansys Collaborate to Deliver Design-to-Validation Workflow for Spacecraft Charging

Streamlined simulation solution accelerates spacecraft charging and ESD analysis for design evaluation in space plasma environments.

Lakewood, CO, October 25, 2021 – Electro Magnetic Applications, Inc. (EMA) and Ansys have collaborated to deliver Ansys EMA3D® Charge, an enhanced design-to-validation workflow to assess and manage risks associated to material charging in space plasma environments. As testing of spacecraft charging in orbit is nearly impossible, this workflow reduces the risk of mission failures by tackling the surface and internal charging analysis at the design phase.

EMA3D® Charge is a robust, platform-level surface charging, internal charging, and ESD modeling solution that delivers an extremely streamlined approach to assessing and managing risks in space plasma environments. When used early in the design stage, EMA3D® Charge can empower engineers to quickly and accurately predict the spacecraft’s ability to mitigate charging, radically reduce physical prototyping, and cut development costs.

“There is an increase in commercial interest in space, with new constellations of low-earth orbit satellites, space tourism, and a mission to the moon,” said Tim McDonald, President of EMA. “All these new vehicles must consider space environment effects in their design and verification. EMA3D® Charge is the first commercial tool to provide support for this important engineering effort.”

Analysis of spacecraft charging due to low and high energy plasmas of GEO and LEO environments, solar wind and illumination, thruster plumes, lunar dust, and more, is a critical design step. The electric fields created between solar cells and busbars, between the spacecraft and the surrounding plasma environment, or within exposed dielectrics may be high enough to initiate arcing and cause permanent material damage or worse, a total mission failure.

“EMA3D® Charge fills a need in a marketplace in which no other simulation product exists,” said Shane Emswiler, Senior Vice President of Products at Ansys. “Engineers simulating charging and discharging events once had to navigate multiple codes and challenging workflows that fell short of a full solution. EMA3D® Charge is a full solution – one that provides highly accurate analysis and end-to-end workflow designed for efficiency.”

“EMA3D® Charge has an impressive array of capabilities,” said EMC Engineers at NASA Johnson Space Center. “For example, its ability to easily manipulate and mesh mechanical computer-aided design (CAD) models greatly simplifies the process of going from a structural model of the spacecraft to analytical results. We have also seen great value in its ability to perform charging analysis on spacecrafts that are being charged by direct contact with lunar dusts while simultaneously being charged from exposure to space plasmas on or near the lunar surface.”
