Syntax

Magnetic Pressure [{of} SpeciesName] = Exponential ([Toggle = toggle] | Variable = variable | [Constant = constant] | [Multiplier = multiplier] | Exponent = exponent)

Scope

Aria Material

Summary

Value from an exponential function

Description

The value, $\phi$ , is calculated as $\phi = C + M e^{k X}$ where $X$ is the variable, $C$ is the constant, $M$ is the multiplier, and $k$ is the exponent. $C$ and $M$ are optional and default to $0$ and $1$ , respectively, if omitted

The following options are present in most boundary conditions/sources. The meaning of each option is as follows:

Toggle: If given, specifies which toggle block controls whether this BC is active or not.
