Hi I’m simulating 2 spiral coils with each having I-in and -out (there are 4 i in a whole region )and I can’t assign matrix in parameter … what do u recommend?
@@viswashh Hi Bishwas. I followed the exact instructions in the two tutorials on how to get inductance of a coil. However, when I simulate, I get this error :"Error in calculating the conduction paths. The most likely reason is that the mesh of the source conductor is wrong. (4:14:46 PM Mar 26, 2021) [error] Simulation completed with execution error on server: Local Machine. (4:14:47 PM Mar 26, 2021)" Any suggestions on what I could be doing wrong? Thanks in advance.
@@lesediplaatje8832 This is happening with the same wire diameter? Please try to simulate with a thicker wire diameter once. Or you can also change the Maximum element size in mesh to some smaller values. Or Maybe you can right-click and change the "Initial Mesh Settings" to "Auto" mode. Do these things one at a time to know where the problem is coming from.
Thanks for the reply. I tried all the suggestions above, but it still didn't work. I did the tutorial from the beginning and found out my boundary area(box) was small and I did not make it big enough as mentioned in the video. Thanks for the help.
Hii bro, i am geeting error while creating matrix .." no valid sources could be used to matrix setup" although i have created excitation ...can u please help? TIA
How would one model a coil with multiple layers. Would you generate multiple helixes and then join them together ? I'm thinking like a transformer coil where you layer windings to maximise the volume of coper wire.
@@viswashh Piling up coils would increase the height and as a result the fields would decay (or am I missing something - vacuum ???). If correct then I believe my assumption is the answer then ? One of the issues I see with piling up coils is that you don't get magnetising fields induced in the coils. In the expanding coils case you would cause induced current into the inner coils, hence higher magnetic field strength. Ie multiple winding layers is more efficient.
I have a question at the beginning of the video, you said you were going to show us how to move from the helical coil to the spiral shape. Please explain how to do this.
Hello, thanks for the video, I have a question about of results, I tried to follow the same process but the software shows the message "Adaptive Passes did not converge based on specified criteria", do you know the reason?, in the video, you show the result of another project "AirCoreInductror" this project have any difference? greetings.
Yeah, I switched to another project whose result was ready there. But the error you getting Is basically because of Mesh size. Please try to take other values than you are trying right now: smaller will be better. Also, please make sure you turning on the Iterative solver while creating the analysis setup. I hope it helps. If not please revert back to discuss.
@@viswashh Hi, thanks for the answer, the iterative solver is turned on. The software already solved the problem but I had to change the -initial Mesh Settings, on the meshing method I changed Auto for Ansoft Classic Mesh, the difference is the result, because the software calculated 30.284160 uH with 5 A that your example.
For those having an issue with the mesh size, I found that changing the number of polygon segments of the coil from 0 to 6 will fix the issue, creating a hexagonal coil rather than cylindrical. 0 creates >100,000 mesh elements, where the student version is capped at 64,000. I also imagine the meshing algorithm is much more complicated for a cylindrical coil than it would be for a cylindrical wire, or hexagonal coil. I found that changing the other settings didn't bring the number of mesh elements down as much as I needed. I got 30uH for the result
Thats indeed true. You can opt for 36 segments which is default btw so that the shape is also not that much away from becoming round. Segments will keep the symmetry intact and meshing easier for the system as well.
Thank you for the very useful tutorial. But when I simulated, i met this error. What does this means, Sir? "Mesh could not be made watertight on the conductor surface Simulation completed with execution error on server: Local machine". Now i am using a 2021 cracked version.
Hello, thank you for the video, I have a question about of results, I tried to follow the same process but the software shows the message "Mess Size exceeded the Limit", and also showing "Unable to save current mess data for simulation: %1" If you know kindly tell the reason.
I am really sorry to say that I have never simulated a Generator in Ansys but we can collaborate and share models to learn quickly. So feel free to email me with relevant details and models you created. so that we can move forward.
Bishwas, you did a great job and I thank you for the sound illustrations. I have the ANSYS Student version thus, limited to only building the models. See error message "[error] Setup1: Mesh size (83339 volume elements) exceeded Ansys Electronics Desktop Student limit. (5:38:06 PM Feb 26, 2022) [error] Simulation completed with execution error on server: Local Machine. (5:38:07 PM Feb 26, 2022)" Could you tell me what I could change in the coil to be able to run a simulation (maybe reduce the amount of turns?) OR can I not do Maxwell 3D simulations on a Student version? Thanks again!

Very helpful tutorial. Thanks alot!
I am glad that you liked it. I will be uploading tutorials for Wireless power transfer too very soon. Please watch that too if relevant.

You can draw it manually. Or pile up coils onto each other as per your need.

Hello Biswas
Can you help me in magenostatic simulation.
When iam trying to perform , it’s showing an error.
Please email.
Which software we have to use
I have a question at the beginning of the video, you said you were going to show us how to move from the helical coil to the spiral shape. Please explain how to do this.
Its in menu list DRAW >> Examples >> User Defined Primitive >> Spiral (Python)

@@105juanpi Nice to hear that.
How can i get the inductor results with mH , give me a critical way to this problem
You can always change the units just by clicking in UNIT table heading

"Mesh could not be made watertight on the conductor surface

dear sir,may i ask you are you still update your video right now ? it will be my pressure that you reply me.

I am unsure. Please try changing the mesh size. Maybe reduce it, make it finer.
I have the same problem. Did you find any solution?
Can ou guide me how we can set animation of a generator in ansys maxwell and see what nature of volatge and power is generated.

Maybe you can make the mesh more coarse. Take bigger values. Or just take help from crack versions to get past this problem ultimately.
Ok will try again. Thank you!
thx！helped me a lot！
Can you help me with spiral coil
its creating >100000 mesh elements, but student edition is capable of 64000 only. can anyone please help
Sir i can't see the results ,and I am now using Ansys 2024 r2 /Student
Bishwas Basnet: I sent you an email and comment here, but you did not reply me? I am still waiting for your response ?
ansys maxwell or ansys electronics
Both are same. Ansys electronics is the software package which includes Maxwell.
and yeah....well yeah...
