is there any possibility to initialize the Hopfion (3-D Skyrmion) like we did with neelskyrmion(1,-1) ?  



Thankyou in advance

regards,
VIJAY R

Hi,

The most recent mumax release has HopfionCompactSupport(float64, float64). Otherwise I don't think there is a built-in function, but of course you can always build it up using other configurations and relaxing, loading an OVF file, or using a vectormask.

Best,
Josh L.
