EMC Plus: HIRF Coupling to an Aircraft Demo (Part 2)

Hello everyone, this is Adair from OZE Engineering. In the first part of this demo, we defined our simulation domain, the plane wave source, and we also defined and assigned materials to our model. Now the next step is to create the mHARNESS cables.

To do that, let's start by hiding all objects and only keep the wires. So I'll click on the eye icon here, and we'll click here to show the wires. I will also hide the domain by clicking here.

Now we can see our wires, and if I go here in the structure tree and expand wires, we can see that we have spline 1 and spline 2. Now let's select the mHARNESS tab, click on cabling, and select overbraid. Here we'll select spline 1, and we'll add endpoints.

Then here, let's click on library, expand general, and let's select the 0.79 mm, and click OK. Now we can click complete. Here in the simulation tree, we can see overbraid 1 under Harness. Now we will create a 26 AWG twisted shielded pair within the overbraid.

So let's right click on overbraid 1, go to add, and select shield. Here I'll select spline 1, and let's click here, go to library, expand general, and under TSP, let's select the 26 gauge TSP. And click OK. Here I'll click complete. As you can see, now we have shield 1 in the simulation tree.

Now to add a conductor inside the shield, let's right click on shield 1, add conductor. Here we'll select spline 1. Let's click here. Go to library, general, bare wire, and we'll use a 26 gauge wire. Let's click OK.

Here we'll add endpoints, and we'll go to terminations to change the resistance of the endpoints to 50 ohm. And now we'll just click complete. To add a second conductor of the TSP, let's right click on conductor 1, and click copy.

Now if we go to inspect our section button, and hover over the wire, we can see our cable. Now to add an additional TSP to the overbraid, let's right click on shield 1, and click copy. If we inspect our cable, we can see that we have the additional TSP there.

Now we will construct the harness for the spline 2 cable, and to do that, let's go to cabling, overbraid. Here I'll select spline 2. And here we'll add the overbraid. And here we'll add the overbraid. And here we'll add the overbraid. And here we'll add the overbraid.

And here we'll add the overbraid. Let's click here. And we'll use the same 0.79 mm. And click OK. Here in the simulation tree, we can see our overbraid 2. Now we are going to construct a coax cable and a twisted shielded triple inside of the overbraid.

To do that, let's right click on overbraid 2. Add shield. We'll select the more overbraid. Spline 2. Let's go to the library. Expand general, and let's expand singles. And select the 24 gauge single. And click OK. And click OK. Now to add a conductor to the new shield, let's right click.

And now to add a conductor to the new shield, let's right click on it, and select 24 gauge single. And click OK. Click on sheath 3, add conductor. Let's select spline 2. Click here and let's go to library, expand general, their wire, and we'll select the 24 gauge wire, and click OK.

And click complete. Now to construct the TST, we will select a default cable from the mHARNESS library. So let's go to overbraid, add cable. Now we'll select spline 2. I'll click here and click here and click here and click here and click here and click here.

Let's go to library, expand general, and let's go to TST. Here we'll select the 20 gauge TST. Let's click OK and complete. Now if we go to inspect our section, and here we can see the cable cross-section as you find in the example.

Now that we have created our mHARNESS cables, let's create our current and voltage probes. To do that, let's go to cables, select current. Here I'll select spline 1, and up and down from the origin to the current cable, 80 percent there.

We'll select one on the company, and in here, we can select one on the company. This is going to Roma. We'll select the cable, and let's go and click OK under the bandar kabailu, the level. Now we need to repeat the same steps to place the current probe on the spline 2 cable.

So let's click on cable current, let's select spline 2. Please select the clothes there. We'll select change flow to Coulomb Arabic flu if you saved in US and give that handle in a past mail path layer 1 and click OK. Now let's set up the voltage probes.

To do that, let's go back to cable, and click voltage. Here we select spline 1. We'll place the probe somewhere in the middle. And we'll select layer 3 and select conductor 1. Then click OK. Now let's repeat the same steps for the spline 2 cable.

Here in layer 3, we'll select cable C0 and click OK. Now we'll create the electric field probes that will capture the fields inside the canopy. And to do that, let's go to the EME 3D tab and go to field. Here we'll select boxed region. Let's expand bounds, minimum and maximum.

And let's set them as follows. We have xmin, ymin, zmin, and set this as 0. So we'll use this in one of the EME as well. We'll go to the next column in our third column. And again, we'll specify fields. Here, we've multiple elements to take, such as this.

Now we just want to make sure we have the family 3 and 3. If we've made any changes to the columns, let's just verify the faq that we want. So as far as the extrusion directions and here you go. You can see the separator problematic for screenshot.

So we'll use protocol toleo active and mega syntax, try control. Now we are ready to mesh the model, so let's click on the mesh button. Here we can right click and select inverse visibility. This would allow us to more easily view the model. And here we can see the mesh.

And now let's click on the start button to run the simulation. And click run. Now that the simulation completed successfully, let's close these windows. And now let's close these windows. And now let's close these windows. And let's go to results. And let's go to results.

We started by plotting the results from the feed probe. So let's right click on feed probe 1. And click compute feed statistics. Here we select the planewave.dat file. Click open. And we keep the x, y, and z directions. And we keep the x, y, and z directions. And we keep the x, y, and z directions.

And we keep the x, y, and z directions. Now and here as you can see, we have the results from our feed probe. And here as you can see, we have the results from our feed probe. Now let's go back to results. And let's plot the results from the voltage probe.

Let's right click on voltage probe 1 and click plot. And here we see the results from our voltage probe 1. In this video, we saw how to create and run these cables, create current, voltage and feed probes. We saw how to mesh and run the simulation and plot the results.

This completes the HIRF coupling to an aircraft demo available in software examples. Thanks for watching and see you in the next video.
