Classes
struct	CoefficientEval
struct	f_asm_data
	Partially assembled data type for one element with the given number of quadrature points. This type is used in full element matrix assembly. Stores one general (non-symmetric) 3 x 3 matrix per point. More...
struct	p_asm_data
	Partially assembled data type for one element with the given number of quadrature points. This type is used in partial assembly, and partially assembled action. Stores one symmetric 3 x 3 matrix per point. More...
