Q3D Features Presentation
Hello everyone, this is Daniel Esmaili on behalf of Ozen Engineering, Inc. I'm going to show you some additional features of Q3D. This is a continuation of the Q3D series video that we're putting out on our channel. As mentioned before, we are a light channel partner of three years in the whole US: 2015, 2018, and 2021. We cover structure, thermal, fluid, electromagnetic, and photonic domains. If you need any assistance with software or consulting projects, please feel free to reach out to us.
Today's Presentation Overview
In today's presentation, I'll cover the following topics:
- Geometry adjustments
- Changes in the sweep to improve results
- Matrix reduction
- Result analysis
Geometry and Sweep Adjustments
Let's jump to the model. As you notice, everyone looks interested in checking out the new gear on Q3D. The first thing we'll address is the setup, especially the sweep part. Currently, it starts from 0.01 GHz and goes up to 2 GHz. We're going to add two rows here to extend the spectrum and include the DC part.
- Add a row above, changing the start to 0 and the end to 0.1 GHz.
- Set 51 points for this range.
- Extend the sweep to 10 GHz by adding a row below, starting at 2 GHz and ending at 10 GHz.
- Choose between log scale or linear scale; for now, we'll use linear.
After running the results, you'll see the curve extends all the way to 10 GHz, providing more comprehensive data.
Matrix Reduction
Next, we'll make changes in the matrix, specifically matrix reduction. Initially, there's nothing under the reduced matrix, only the original one. We have a small die and a big die, with induction AC RL and DC RL. Some customers might be interested in knowing the value if these two are electrically connected.
- Connect them in parallel if the current flows in parallel; otherwise, use series for series connections.
- Select the small die and big die, and join them in parallel.
- Rename them appropriately to avoid confusion.
Once saved, you'll see two matrices: the original and the joined parallel. This is useful for analyzing combinations of sources and sinks.
Conclusion
We hope you find this video informative. In the next video, I'll demonstrate another use of these features. Thank you for watching!
RLCG Calculation for Parallel Leads using Q3D Matrix Reduction
Hello everyone, this is Daniel Esmaili on behalf of Ozen Engineering Corporation. I'm going to show you some other features of Q3D. This is a continuation of the Q3D series video that we're putting out on our channel.
We are a light channel partner of three years in the US, covering structural, thermal, fluid, electromagnetic, and photonic applications. If you need any assistance with software or any consulting project, please feel free to reach out to us.
In today's presentation, I'm going to show you the following: 1. Geometry and making changes in the sweep to make it better. 2. Matrix reduction. 3. Results. We will first look at the model we worked on last time. If this is new to you, feel free to check out our last YouTube video.
The changes we are going to make today are in the setup, specifically in the sweep part. It starts from 0.01 GHz and goes all the way to 2 GHz. We will add two rows here, making the spectrum higher, and include the DC part.
To do this, you can: 1. Select the first point. 2. Click "Add Above." 3. Change the start to zero and the end to 0. 1. 4. Add 51 points. Now, we want to make this go all the way to 10 GHz.
We will add a row below, with the start at 2 and the end at 10. We can save it as 101 and change it to log or linear scale. Let's save it as linear for now. Next, I will run the result. As you can see, it goes from 0.01 all the way to 10 GHz.
With this improvement, the curve will go all the way to 10 GHz. We will also make another change in the matrix, called matrix reduction. When I click here, there is nothing under "Reduced Matrix." However, there is only one, the original one.
When you look at it, you will see the small die and the big die, as well as inductance AC RL and DC RL. Sometimes, customers need to know the value if these two are connected together electrically. Let's try to do that here.
We will connect them together, and if the current is flowing this way, they will be in parallel. Therefore, we will use "Join Parallel." If they were in series, we would use "Join Series," and there are other features here that I will explain in the next video.
For now, let's say "Join Parallel." Here, this die is called a small die, and the other one is called a big die. We can choose all three of these together and then call it "Join Parallel for Small Die." We will do the same for the big die. We can name these whatever we want. Save and close.
Now, when I go here, I see two matrices, and these are all post-processing. Once you solve the problem, there is nothing else that needs to be done.
Right-click here, go to "Matrix," and you will see a drop-down menu with "Original" and "Join Parallel." You will see how the result looks if this is confusing. Let's make it simpler. We will delete this one and stick with the small thing. Look at the matrix again.
You will see that it's all four guys over there, and they are all deleted, except for the small die. There is only one row left. Let's look at the inductance. This is the inductance. If you want to sell it, you will see the self-inductance of the part is 3.7 nH.
For the others, it's just individual, one by one. This is useful when you want to have a combination of two or three sources of sync and understand how the combination of them will work. I hope you like this video. In the next one, I will show another use of this feature.
Don't open anything except during the presentation. Thank you.
