HIRF Coupling to an Aircraft

This training instructs users through preparing a HIRF problem in the current EMA3D workflow. A model of an F-16 Fighting Falcon has been prepared for this simulation. This preparation included model simplification and surface cleaning to ensure mesh is representative of the model, and cable simplification for the use of EMA3D’s cable harness solver MHARNESS. […]

HIRF Coupling to a Cockpit up to 18GHz

This tutorial is a step-by-step demonstration on how to perform a HIRF simulation in the current EMA3D workflow. A model of an F-16 Fighting Falcon cockpit has been prepared for this simulation. This preparation included model simplification and surface cleaning to ensure mesh is representative of the model, and cable simplification for the use of […]

Crosstalk Simulation

Cables that are co-bundled or routed near one another may induce electromagnetic interference (EMI) in one another through fields. This phenomenon is referred to as cable crosstalk EMI. EMA3D’s cable simulation tool, MHARNESS, is capable of performing simulations of crosstalk between conductors with arbitrary signals either in the same or in different harnesses. The demonstration […]

Model Simplification and Preparation for MHARNESS Co-simulation

This tutorial is a step-by-step demonstration on how to prepare and perform a full aircraft simulation. We go through how to simplify CAD geometry of cable-packs down to lines to be used in MHARNESS, and the steps to prepare a model for a co-simulation with EMA3D and MHARNESS. MHARNESS is a transmission line solver that […]

CADfix and EMA3D HIRF Training

  By Eric Miller Click Here to download training file. The Training can also be viewed below. The purpose of this training module is to build familiarity with the basic functions of CADfix and EMA3D. By building a very simple plane model, you will learn basic geometry creation and modification techniques. Due to the limited […]

DO-160 test setup

DO-160 Cable Susceptibility Test and Simulation

By Jennifer Kitaygorsky, PhD and Anthony Supino You can open the training document here. In DO-160 chapter 22 (and sometimes chapter 20) testing, it is often advantageous to use simulation to help understand what is happening inside of cable shields and equipment. DO-160 test waveforms that are injected onto complex cable harnesses will induce currents and […]

Introduction to EMA3D and CADfix

By Eric Miller Click here to download training files In aircraft development, significant resources are spent to ensure safety during a lightning strike. Experiments are very costly and it’s impossible to measure every interesting quantity at every location. With lightning simulations, a more complete data set can be taken (all field values can be known in […]

Aircraft P-Static

By Anthony Supino Aircraft Precipitation static (Aircraft P-Static) is a term used to describe interfering noise resulting from the redistribution of charge on an operating aircraft. As an aircraft moves through the air, it acquires charge until sufficient voltage levels are reached to initiate a discharge. This discharge may occur between different parts of the […]

EMI from a Slot in a Box

By Cody Weber and Bryon Neufeld Benchmark Simulation Using EMA3D It is important to demonstrate that EM simulation packages can reproduce measured data for problems of interest. EMI from a slot is a common EMC concern. This demonstration compares an EMA3D simulation to an existing measurement in the literature. The electromagnetic interference (EMI) from a […]
