Syntax

Bc Flux For Continuity ([{of} SpeciesName] | [{in} MaterialPhaseName] | [{ls} {a | b | c}]) {@ | at | for | on | over} Mesh Extent Name ([Touching TouchingMeshExtent] | [Opposing OpposingMeshExtent]) = Exponential [Using Data Specification Data Spec Name] (Variable = variable | [Constant = constant] | [Multiplier = multiplier] | Exponent = exponent)

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
