EMA3D Shielding Effectiveness of a Box Demo
Introduction
Hello everyone, this is Adel from Ozen Engineering, Inc. In this video, we will explore the EMA3D cable shielding effectiveness of a box demo, which is available in software examples.
Objective
Let's consider a simple geometry consisting of a box with a small aperture. Our first objective is to set up the problem space and then proceed with the EMA3D cable workflow. This workflow will allow us to model the interaction between a plane wave and the box, enabling us to analyze the internal electric field and determine the box's shielding effectiveness.
Interface Overview
- In the discovery interface, located in the top left corner, we have the structure tree. This tree contains all the individual components of our geometry.
- Below, we have the stage explorer. To access the EMA3D stage, click here and select EMA3D from the available options.
EMA3D Workflow
- Once in the EMA3D stage, proceed with the EMA3D workflow.
- Click on the EMA3D tab located in the ribbon at the top.
- Click on the Domain button to open the simulation tree, which displays all the different steps of the EMA3D workflow as we progress through them. The simulation tree also allows us to edit any of the steps as needed.
Properties Panel Setup
- Go to the properties panel and expand Time and Lattice, minimum and maximum.
- Keep the stability margin to 15% and adjust the lowest and highest frequencies:
- Set the lowest frequency to 10 megahertz, which will automatically adjust the end time.
- Set the highest frequency to 500 megahertz, which will automatically adjust the step size in both time and space.
- Ensure all pieces of geometry to be meshed are encapsulated within this lattice. The box should be entirely encapsulated by the lattice with a little bit of padding between the boundary and the model.
Final Steps
In the properties panel, select the L cortex for the H masculinity. Then, select a linearesta for the Y box for the obsoleting specified подготов layer. Save all values, including amount and depth. Once the values are selected, click on the green checkmark to complete the domain setup.
Hello everyone, this is Adel from OZENgineering. In this video, we will explore the EMA3D cable shielding effectiveness of a box demo, which is available in software examples. So, let's consider this simple geometry, which consists of a box with a small aperture.
Our first objective is to set up the problem space, then proceed with the EMA3D cable workflow. This workflow will allow us to model the interaction between a plane wave and the box, enabling us to analyze the inside electric field and determine the box's shielding effectiveness.
Here in the discovery interface, located in the top left corner, we have the structure tree. This tree contains all the individual components of our geometry. Down here, we have the stage explorer. To access the EMA3D stage, click here and select EMA3D from the available options.
Once we are in the EMA3D stage, we will proceed with the EMA3D workflow. To begin, click on the EMA3D tab located in the ribbon at the top. Next, click on the domain button. This will open the simulation tree, which displays all the different steps of the EMA3D workflow as we progress through them.
The simulation tree also allows us to edit any of the steps as needed. Now, let's go to the properties panel and expand time and lattice, minimum and maximum. Let's keep the stability margin to 15% and adjust the lowest and highest frequencies. We set the lowest frequency to 10 megahertz.
And as you can see, it will automatically adjust the end time. We set the highest frequency to 500 megahertz. And this will automatically adjust the step size in both time and space. Now, we need to ensure that all pieces of geometry that we want to mesh are encapsulated within this lattice.
So, the box should be entirely encapsulated by the lattice with a little bit of padding between the boundary and the model. Here in the properties panel, we will select the L cortex for the H masculinity. So, let's go ahead and select a linearesta for the Y box for the obsolete layer.
To save all values, click "Apply," not "I willandid物 , amount, and depth." Now, when we select the values, let's ensure that we have the correct variables. Here, we will start with the drivers, the angle, and all medium. Then, we can read these to describe the variability.
Once this is done, click on the green checkmark, which completes setting up the domain.
