Circular Distribution Functions

Simulation: Sources and LoadsParticle SourcesParticle Circular SourceRadial Dependency

This dialog box allows to define parameters for the radial distribution functions of circular particle sources.

Since the total amount of emitted charge is not changed when using a distribution function, the following constraint appears:

Rout : outer radius of the Circular Particle Source

Rin : inner radius of the Circular Particle Source

f(r) : radial distribution function

This equation is used to scale the distribution function. This means that the scaling factor cscale will be computed automatically.

Equation Display

This window shows the equation of the radial function and it's parameters.

Parameter Boxes

The parameter boxes can be used to define the important values of the radial functions.

The meaning of the parameters depends on the previously selected function type:

Gaussian:

Offset: Function value: at r =0: coff.

Sigma: Standard deviation sigma

The scaling value cscale for the gaussian part of the distribution function is calculated automatically.

Note: If the function offsetat r=0 is set to one the scaling value will be zero and therefore a constant distribution is taken.

Polynomial:

Offset: Function value: at r =0: coff.

Order: Polynomial degree n

The scaling value cscale for the polynomial part of the distribution function is calculated automatically:

Note: If the function offset at r=0 is set to one the scaling value will be zero and therefore a constant distribution is taken.

Accepts the changes and closes the dialog.
