EMA3D 2020R1 Video Demonstration

The videos below will demonstrate the EMA3D 2020R1 workflow for a high intensity radiated field (HIRF) simulation. This workflow includes setting up the problem space, assigning properties, defining probes, and basic post-processing. A fighter aircraft similar to an F-16 will be used to simulate this problem. The aircraft will be exposed to a plane wave of a Gaussian pulse to simulate multiple frequencies at once. This will allow the canopy shielding effectiveness and the coupling onto avionic cables to be predicted.

EMA3D 2020R1 on ANSYS utilizes the product ANSYS SpaceClaim Direct Modeler as its geometry and GUI engine. The EMA3D 2020R1 on ANSYS product is currently available from EMA. Please contact the EMA Sales Representative for your respective region.
