Hi all!
I need to add the magnetic field lines (and possibly add metal bars between the head and emitter) to the model 2190 Absorbed Radiation (SAR) in the Human Brain.
PS Since I'm a beginner, then I ask (if possible) to provide input data for example.

Dima,

Use the following steps to create magnetic stream lines:

1. Results>3D Plot Group
2. 3D Plot Group 1>Streamline
3. In the expression to plot, define Magnetic flux density vector {Bx,By,Bz}, or Magnetic field vector {Hx,Hy,Hz}
4. In the Streamline Positioning section, adjust streamline parameters to get nice plot for magnetic field lines

Good luck,

Sergei Yushanov

Thank you!
But I've done it before. And the result was not granted me.
Maybe I'm doing something wrong?

Hi!

Something like this? You can play a lot with 3D plots ;-)

Hi
You must define a region (boundary) from where COMSOL should seed the generate of the streamlines, typically some place close to your source. Or you select the Uniform density streamline

Hi!
Yes I want that! But somehow nothing is drawn. =(
In the graphics tab - empty!

Hi

check the sub nodes of your plot, something is not set-up correctly, or you are not pointing to the right data set, there can be many things.

Have you gone through the doc to understand what the different tab and entries do ? usually the most important are coming first (on the top)

Hi!

I have cleared the solution to get a small file...you only have to re-run the simulation.

hi, this happened to me too, how did you fix it?
