Making 3D geometry in mumax3

[Sibashish Chakraborty]

Hi everyone,

I want to reproduce the results of the attached paper. Can anyone please suggest how to make the fullerene structure in mumax3? Is setinshape will produce a 3D structure of the buckyball?

Thanks in advance.

With regards,

Sibashish

Hi,

You should be able to construct that structure, but you will have to build it out of the more primitive shapes given in mumax. You can find them in the examples and api pages. They don't have hexagons or pentagons built in, so you will need to build that up from something like a rectangle, using rotations and translations. (You also might be able to do some work with imageshape, but that will be 2-D, so you'll still need to build it up). Once you have a hexagon shape, you can perform another set of rotations and translations to get it into position as the face of the fullerene.

In addition to the basic shapes, you will need the methods of translating and rotating them (also shown on the examples page). It will be a bit of work, but it should be doable. I recommend breaking it up into smaller pieces, and getting those done first. And then exploiting the symmetry.

Setinshape is used to set the magnetization inside of a defined shape. You would still need to design the shape first, but then you can use setinshape to define a magnetization state.

Best,

Josh L.

Thanks for your reply. I shall check it out.

Hello, is it possible to create an ovf file in COMSOL with the geometry and then just load it in mumax3?
