Hi all
i am new the the world of Comsol.
i am trying to develop a solenoid. the aim of the device is to produce a magnetic field inside to solenoid that will be constant.
my question is: Is there a fast way to create the solenoid (3D)

Hi
I would make a rectangle in 2D axi and then revolve into 3D, if you cannot live with 2D axi whixh is easier as it solves so much quicker.
However in this way you do not simulate each coil, but all turn and you must think in amp/turn for your current
Good luck

well this is not a comsol issue "per se" but in choosing the modeling approach you need to be careful about your problem requirement...specifically here..
what "constant" means...?
which % of variation on which part of the volume.....?
depending upon your application these requirements can be very demanding and will force you to do a true 3d model including connectors and so forth....and sometime depending upon the number of turs and the operaing frequency even include a wire description [ insulating layer...]
if not the axisymmetric is the way to go as Ivar pointed it
So yu really have to think about what your DETAILLED requirement need before thinking of a modeling approach
"constant " is not enough in that respect...
the 2 cannot be separated..
