EMA3D

EMA3D is a powerful 3D numerical solver of Maxwell’s curl equations based on the time-domain finite-difference method in rectangular coordinates. The code has application to nearly any EM coupling, radiating, or interaction problem. EMA3D’s FDTD approach is the only EM tool capable of capturing the detail of entire aerospace or ground systems down to individual electronics interfaces in a computationally accessible manner. EMA3D has a sophisticated air conductivity model that considers the plasma fluid nature of air in high electric fields. EMA3D can co-simulate with MHARNESS for a powerful method of determining cable coupling.

This section of the user manual describes the procedure for preparing, solving, and post-processing the simulation in EMA3D.

EMA3D uses Ansys Discovery to draw or import the model geometry, clean the imported geometry, and generate the model mesh.

The EMA3D user interface is a ribbon-based interface as shown below:
