7.17.1.11.4. Exponential

Syntax

Source For Cvfem Mass Fraction ([{of} SpeciesName] | [{in} MaterialPhaseName] | [{ls} {a | b | c}]) {@ | at | for | on | over} MeshPartIdentifier = Exponential (Variable = variable | [Constant = constant] | [Multiplier = multiplier] | Exponent = exponent)

Summary

Value from an exponential function

Description

The source, \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
