Rotman Lens openEMS and Blender Simulation Guide
This video will walk you through how to simulate a Rotman Lens with openEMS and Blender. You will learn how to take advantage of Blender's powerful capabilities for 3D modelling and mesh generation for creating openEMS RF simulations and visualizing results.
I will first cover how to use Blender to generate an antenna model from a basic image, setting-up ports and field dumps and other tips and tricks to ensure a successful simulation run. Then exporting meshes to openEMS and using Blender's python editor to write scripts to handle exporting ports and field dumps setup more efficiently.
Then I will touch on setting up the actual openEMS simulation in Octave, and then visualizing and analy...

70GHz Rotman Lens openEMS Simulation
Просмотров 1,5 тыс.14 дней назад
Attempting to simulate a 70GHz Rotman lens with openEMS, I've used Blender to model the lens, which then I exported to openEMS, and the simulation results are rendered back into Blender. This animation shows the launch of the electric field component from one port and how it propogates throughout the lens. It does seem that most of waves are absorbed at each inactive port, though there are some...

Blender 4.2 SDF Modelling and Elmer Simulation
Просмотров 759Месяц назад
I'm trying the new SDF grid boolean node in Blender 4.2 to model a resistor, and then exporting it to FreeCAD to set-up an FEM heat simulation in Elmer, and then using SDF nodes again to visualise the results, also using Eevee next. Very exciting! Will be creating more FEM simulations of Blender models!! The FEM simulation in Elmer is very basic for now, simply shows the resistor's steady-state...

Ceramic Capacitor Modelling in Blender
Просмотров 3605 месяцев назад
Continuing my work on component generators in Blender, I now can model through-hole ceramic capacitors! One of the issue with modelling ceramic caps in CAD is that you have no control over the spacing of the leads, sometimes you just want to spread the leads further apart or bring them closer. With Blender you now have full control, and you shape them however you want! You can also adjust the p...

PCB Clearance Constraint Rule in Blender - Demo
Просмотров 4336 месяцев назад
I've been developing a tool to implement a PCB electrical clearance constraint rule using geometry nodes. This is useful when creating initial layout and component placement studies especially for high voltage designs. Also, can be used for documentation purposes. You can see in this video how warnings are displayed when components get too close to each other based on whatever clearance distanc...

my antenna design course has many openEMS examples: ruclips.net/video/kEdwACvFaBI/видео.html Beautiful simulation! If some company create EM simulator capable render such things stand-alone without Blender - it would be a killer feature.
This is awesome !
I don’t know how many views you’ll manage to get from such a niche content, but the quality and innovative value of this video is incredible. You’ve introduced me to a whole new area of expertise. I’ve been following you on LinkedIn for many months now. Thank you very much. Your time and efforts are greatly appreciated.
Great material, watching it makes me melt like chocolate in the sun
awesome!
All of your work is amazing!
incredible stuff
Very cool!!!
THX these Simulations are a great way of Visualization. Can you add some explanation to the Videos? For example in this one,at about 0:08 slow down the animation to near stop, "The input port is positioned to the left of the center, resulting in a slight delay shift for the outputs, with the rightmost one experiencing the most delay"
Cómo se llama el programa?
Very interesting, and it looks that you do almost all of them with geometry nodes?
Yes all done via geometry nodes
what a special project you do. good jobs
Absolutely amazing! It might be presumptuous, but might your nodes also include capacitance in the future?
Thanks, yes I will be including FastCap for capacitance simulations
Nice Software, I will certainly try!
thanks
What the fuck this is amazing! Perfectly shows reflections and what they're used for in the leftmost track! I never knew it's used in such a way.
Hi, Can you control an object and make it move and rotate or is this just for the camera?.
just the camera for now
@@samerps I dont use blender but it must work the same way as c4d. How about using two cameras, one is connected to an object and uses your addon and you move and rotate and the other camera is used to "see" the scene?.
@@samerps What Im looking for is a way to use the left stick to move up, down, left and right and the right stick to rotate. This would be nice to play test game levels.
@@pnvgordinho yes that should work straight away, you can set that up easily in Blender
The four patch array antennas here are typically the receive antennas not the transmit antennas. I also have to wonder what parameters you used for the dielectric properties of the hand, the permittivity seems like it might be somewhat high. Though these parameters do make for a good demonstration of Zenneck surface waves.
Yes the patch antenna in the video are actually the receive antennas. I used them as transmitters in the simulation just to reduce the size of the simulation domain
Sam, we are waiting a course about the workflow for simulation in blend. 😅. Great work.
100%. Also with the openEMS extension :D
Amazing stuff! Thank you for sharing!
Just to make sure, there was no sound right? I’ve got tinnitus.
No, there's no sound
@@samerps thank you. It looks great btw.
Is reactor weldenstein???🤔
No
Thats really cool
Amazing! How do you accomplish this? I would love a tutorial or even just some quick notes on the process!
Blender should just pivot to MCAD at this point, there's no good MCAD package in linux
Can you do Infineon’s BGT60TR13C next? Lovely work😃
Gonna connect a 60GHz signal to my body so I can look like a god to anyone looking at me with radio vision.
Hi, Sam. Can this generator be used to export in a .step file for use in Alitum? Thanks.
No I'm afraid, only supports KiCAD
where is the addon ??
On Blender Market and Gumroad

Disliked for that ugly MicroUSB connector, should have used TypeC. Nice simulation by the way.
It says 2.92mm, but you put SMA on it!!
Thanks for spotting the error
Wow, great work
Hi, Sam. I didn't found the project in Altium Community. Can you share the link here in comments? Thanks.
here is the link altium-community-projects.365.altium.com/designs/1E9D600A-64C1-48B4-B23B-92025CCC8BAF
Underrated channel
so cool, that's great!
Simulation or animation? Did you use some other software to simulate and blender to visualise?
Yes simulated in openEMS and data rendered in Blender
This is awesome!
how did you do that amazing animation?
This was done in a software called Blender
Any links/updates? Im kind of interested in this.
this should be published on Altium's website resources.altium.com/projects. In the meantine if you have Altium365 you can view the project files
This kind of technology was made by Sony over 20 years ago in Walkman cassette players... So it's not an invention😅
Nice
Can some aspects of this design be shared? If so, can you send us a link. I would like to learn more about the technical details of the design.
The entire design is available from EPCs website
@@samerps thanks. Can you please post a link?
epc-co.com/epc/products/evaluation-boards/epc9174@@Baraka-yl2dp
@@samerps thanks. Much appreciated it.
So cool!
🎉wow
Lovely
Very impressive. I think those four antenna elements included in the visualization are actually individual receiving elements. Your simulation treats them as a transmitting phased array. Transmission with this kind of radar is done using one of the other 3 antennas, only one at a time.
Thanks, yes that is the correct, I've simulated the receiving elements as transmitters because the simulation would be easier, the simulation domain would be smaller
Agree, it gives a good picture of the receiving lobe.
