[Archive] Emissive Sphere

Message by Alexandru Cornogolub:
Hi,
I’m modelling an electron emissive sphere. I would like to see the effect of the space charge on the emitted current. Everything goes well. However I can’t see any emitted particle in the results. For example the emitted particles density is zero. Does someone know what could be the problem? Thank you very much.

Hi !
Have you tried to defined the electron current density of your source to a negative value ?
If not then that is probably your problem.

No, I didn’t…I will try.
Thank you!

Well everything works now! However when I apply a magnetic field the simulation doesn’t converge the progress bar remaining zero all the time. Does someone know what could be the problem?
Thank you in advance.

Hi,
When I include a magnetic field in my simulation which consists basically in a spherical electrode emitting electrons the simulation does not converge.
Someone knows what could be the problem?
Thank you!
