doubt about loading time of a geometry from an analytical function

[Arturo]

Hi,

I would like to create a geometry in mumax3 defining it through analytical function. In oommf generally for a complicated geometry it takes 5 minutes, but in mumax3 it takes more than one day, is there any efficient way to do this?

To create the geometry in mumax3 I use the following code:

setgridsize (300, 20, 300)
setcellsize (2e-9, 1e-9, 2e-9)

Nx: = 300
Ny: = 20
Nz: = 300

AA: = cell (1,1,1)
for i: = 0; i <Nx; i ++ {
for j: = 0; j <Ny; j ++ {
           for k: = 0; k <Ny; k ++ {

r: = index2coord (i, j, k)
x: = r.X ()
y: = r.Y ()
                 z: = r.Z ()

fun: = something

if fun something {
AA = cell (i, j, k) .add (AA)

}


}}}

setgeom (AA)

Generally using for loop is not very efficient.

Thanks

Typically, if one thinks that mx3 script is too slow for certain tasks, then our suggestion is to switch to the Go (computer language mumax3 is mainly written in). These days mumax3 binary accepts .go files and takes care of them similar to the .mx3 ones. For the example you might look into the test/ folder of mumax3 sources.

Thanks, another option would be to load a geometry from an ovf file, can this be done in mumax3?

Yes.

which would be the commands?, 

geo = loadfile ("geometry.ovf")

Setgeom(geo)

I think the previous code does not work.

Hi, finally the code work?

geo = loadfile ("geometry.ovf")

Setgeom(geo)
