Dear mumax community, We are happy to announce the release of mumax 3.12, which includes a variety of

Hello everyone, I am working on a polycrystalline micromagnetic model in MuMax3. My model contains

Can I extract the self-Kerr of a confined mode directly from mumax3, by driving the mode at

Hello Dr. Neeti Keswani According to the screenshot you shared, the simulation is completed normally;

Thank you so much sir for your valuable suggestion. On Friday, May 29, 2026 at 12:47:21 AM UTC+5:30

Dear Hasos, Scripts from older versions of mumax³ should also work in newer versions of mumax³. You

Hi, Hmm, that does seem a bit strange. It seems like it takes quite a long time for the script to

Oh very nice! Thank you! Στις Τετάρτη 20 Μαΐου 2026 στις 11:49:09 μ.μ. UTC+3, ο χρήστης Josh Lauzier

Hi Aurel, Rather than plotting (E_k – E_0)/E_0 as a function of diameter, I would recommend plotting

Hi, Over the past week, I have been trying to automate the building of Python wheels to simplify the

Hi, The simulation in the provided script is symmetric. After relaxation, the sudden excitation

Thanks a lot! The discussion link you shared is very helpful. 在2026年5月8日星期五 UTC+8 17:17:23<Ian

I've updated the notebook using @josh's suggestion, so everything works again out of the box.

Hi, If you update the first cell from: try: import google.colab except ImportError: pass else: !wget

Hi, It could be that you are running into a bug that has recently been fixed. This fix is included in

Hi Josh, Thank you so much for your reply! I wanted to share an update if it's helpful. The

Hi Josh, Thank you very much for your helpful suggestion. Following your advice on implementing

Hi, Scale is a parameter that multiplies the existing exchange between two regions (which by default,

Dear MUMAX3 developers and community members, I am writing to share recent GPU benchmark data

Dear Josh, Thanks a lot for your clarification. I will also check the paper you mentioned. And I may

Dear Felipe, Thank you for your previous explanation.I want to implement a biaxial anisotropy with

Hi all, I would like to ask two questions： 1. If I want to obtain the spin wave energy flow in mumax3

Hi, By default, mumax doesn't have anything built in to handle TI's. I think you'd have

I constructed two magnetic domain walls on a nanowire. In one of the domain walls, I excited spin

Hi, In mumax, you do not set the exchange length (either the normal exchange length, nor the

Thank you so much! This approach worked perfectly for my simulation. I really appreciate your help.

Hi, By default, mumax only has one fixed layer. You'd have to modify the source code for multiple

Hi, In this use-case, J is not directly a spin current. It is a charge current that is used to get

I was trying to mimic this experimental work on simulation . But due to different wave vector it is

Hi, You can do this as something like (assuming the excitation is in x and the bias field is in z.

Hi, This looks to be related to a change made in 3.11 to restrict the demag field so that B_demag=0
