Greetings!

I have spent a lot of time in doing all kinds of manipulations with magneticFoam and finally I have almost come to the end. There is only one totally unclear line for me in createFields.H

const surfaceVectorField& Sf = mesh.Sf();

Mrf[facei] = Mri*(orientationi & Sf[facei]);

I guess my problem is more about C language not about magnetic field physics.

My questions:
What should I get out when these lines are compiled? I get surfaceScalarField in output, but shouldn't there be VectorField? What the first line defines, where information about this mesh.Sf will be taken from?

Mri is a constant, what should happen when I multiply a constant with those parameters in brackets? Also, there is orientation (that is some kind of vector) and then there is '&' symbol. Does it mean Mri is multiplied with orientationi and Sf[facei] in the same time?

Yours sincerely,
Martin
