Detailed Description

template<uint dim>
class concepts::ParsedFormulaBase< dim >

Parses the given string and evaluates it on request.

The following operations and functions are allowed in the formula: + - / and *, (), ^ for exponentiation (also with broken exponents but only with positive bases) and the following formulae:

• sin
• cos
• atan
• sinh
• cosh
• sqr
• sqrt
• exp
• ln

x, y and z are allowed as variables and pi is defined.
