Detailed Description

template<int spacedim, class Value>
class FieldFormula< spacedim, Value >

Class representing fields given by runtime parsed formulas.

Using libraries: https://github.com/flow123d/bparser/

Allows parsing:

base variables: coordinates (x,y,z), time (t), surface depth (d); constants: e, pi
standard functions: trigonometric functions, min and max function, exponential function, ternary operator etc.
expressions dependendent on other fields
