The parameters for the fixed emission model can be changed within this dialog box. A detailed model description can be got from the particle emission model overview page.

Kinetic settings

Kinetic type
Select the kinetic type for further emission properties such as the Kinetic Value (see also Kinetic Particle Settings):
Velocity, Beta, Gamma, Normed Momentum, Energy, Temperature

Distribution
Select if the kinetic settings should be Maxwellian or uniformly distributed.

Kinetic value
The kinetic start  value of the emitted particles. See also the Kinetic Particle Settings page.

Kinetic spread
The energy spread (from 0 to 200 percent) offers the possibility to specify a randomly calculated emission energy. The kinetic emission type (e.g. energy, momentum) is calculated uniformly distributed in the range of:

Angle spread
Determines the maximal deviation between the particle's start angle and the plane's normal. The emitting angle is randomly chosen within the range between 0 and the given start angle limit. See also the Kinetic Particle Settings page.

Temperature
The temperature is used to specify the Maxwell-Boltzmann distribution.

Distribution bins
Specifies the number of different temperature levels within the Maxwell-Boltzmann distribution.

Fixed emission

Select current or current density and enter the desired value.

More or less button

This button allows the user to show or hide the oblique emission settings.

Oblique emission

Note: oblique emission is available only for circular particle sources. For a schematic representation of the oblique emission angles, see the oblique emission section in the Particle Source Emission Model Overview.

Angle theta

The angle theta is formed by the velocity of the emitted particles and the source surface normal.

Angle phi

The angle phi is formed by the component of the particle emission velocity that is perpendicular to the source surface normal and the vector defined by  the center of the circular source and the emission point.

OK

Confirms the changes and closes the dialog box.

Cancel

Closes this dialog box without performing any further action.
