Voulme integral of magnetic flux density

Please login with a confirmed email address before reporting spam

Hi everyone


How can I perform a volume integral of the magnetic flux density (Bx, By or Bz) ?

Does the "Subdomain Integration" perform that?!


Thanks a lot

Hi

the cubdomain integration is ther to integrate any value you put in, the default predefined ones or any valid equation you decide to build upon these.

Its the same for boundary and edge integration, w.r.t. respective dimansional values.

just note that 2D axi requires a 2*pi*r in v3.5 to go from edge to surface integration, erspective surface to volume, while in V4 the 2*pi is already included, pls check carefully, as v4 is still slightly evolving ;)

Have fun Comsoling
