How to open "mumax3.exe"... I can not open it... :(

[‍황영현[ 대학원석·박사통합과정재학 / 전기전자공학과 ]]

Dear all,

I downloaded and unzipped mmax3.10.zip to use mmax3 simulation.

But, after double click on the mumax3.exe file, the empty black cmd window temporarily opened and immediately closed.

Although adding the directory of mumax3.exe to PATH environment, the same situation repeats. 

Even if I open a cmd window and type mmax3.exe, the following appears, but the program does not open.

You can try cmd Windows with command like:

mumax3.exe -i

Have you tried running a script? Like standard problem 4: 

SetGridsize(128, 32, 1) 

SetCellsize(500e-9/128, 125e-9/32, 3e-9) 

 Msat = 800e3 

Aex = 13e-12 

alpha = 0.02 

 m = uniform(1, .1, 0) 

relax() 

save(m) // relaxed state 

 autosave(m, 200e-12) 

tableautosave(10e-12) 

 B_ext = vector(-24.6E-3, 4.3E-3, 0) 

run(1e-9)

Save it in a .txt file and run the comand: mumax3 stp4.txt

Because now, it seems you are not running any script. 

Hope it helps!

Hello, I have worked on mumax3 starting it from the windows power shell using the comand mumax3 -i and writing line by line my script on the gui, because I have not been able to run an entire script. Could any of you explain me in more detail where I should save the .txt file, and how and where should I write the command? I would appreciate it very much.

[Josh Lauzier]

Hello,

You would want to convert the txt file to an mx3 file (literally, just change the file extension. You can do this when you save it in your text editor, or just right click the file in windows explorer).

To call a specific script, instead of 

mumax3 -i

You would write

mumax3 -i nameofscript.mx3

where nameofscript is the name of the file. The file should be located in the same directory as the mumax executable for simplicity. Alternatively, you can give the entire file location. If your mx3 file is located in the Documents folder, you could do something like 

mumax3 -i C:\Users\Josh\Documents\mumax3_10\nameofscript.mx3

And it will work, because it now knows where to find the script. 

When writing the command, it should be written in the same directory as the mumax executable, as you have been doing. Alternatively, you can add mumax to your PATH variable, but that is a bit more work

Best,

Josh L.
