charged particle tracing help needed

Please login with a confirmed email address before reporting spam

hello, i have a simple box with relative permittivity and electric conductivity = 1.
with the mef module i created a magnetic field along the x axis with 10 A/m.
i used a working plane inside the box to create a circlular plain as the inlet surface for the particles.
in the cpt module i gave the particles a starting velocity of 50 m/s along the z axis.
i also added a magnetic force to the cpt module that uses the field created from the mef module.

the stationary study creates the solution for the magnetic field, as expected.

in the time dependent study i excluded the calculation of the mef module as shown in the magnetic lens video
www.comsol.com/video/209

my problem is that i dont get any resulting particle trajectories. the particles just sit on the inletsurface. i just want to see them fly a curve through the magnetic field due to lorentz force.

i attached the file to exclude any misunderstandings, thanks for help
