Define Particle Point Source

Simulation: Sources and LoadsParticle SourcesParticle Point Source

Particle Point Sources can be defined by a picked point or a manually entered position. For each particle point source an emission model has to be defined.

General

Name

Declare the name for the particle source. Each source must have a unique name.

Tracking emission model / PIC emission model

The assortment of emission models is dependent on the problem class. Detailed information of all emission models can be obtained from the Particle Emission Model Overview help page.

Edit...

To modify the currently selected emission model press the edit button and a sub dialog box will open.

Emission special

Emission Area

Since continuous single point sources can also produce a current density in space, it is necessary to assign an emitting surface area to this type of source.

Emission point

Use Pick

If a point was picked before opening the dialog box one can select if the point coordinates should be used to define the start position or not.

Xposition/Yposition/Zposition

To define the start position of the single point source one can enter its coordinates here in global coordinates.

Xnormal//Ynormal/Znormal

The start normal of emitted particles can be entered here in global coordinates.

Particle properties

Particle type

Type of the emitted particles. Available are "electron", "proton" and "userdefined".

Charge per particle

For the user defined particle type, the charge of a single particle can be defined here.

Mass per particle

For the user defined particle type, the mass of a single particle can be defined here.

Load...

Import of particle types form the particle definition library.

Save...

Export of user defined particle types to the particle definition library.

OK

Accepts the changes and closes the dialog box.

Preview

Shows the start position and start normal.

Cancel

Closes this dialog box without performing any further action.
