		const FieldCoefficientsNumber	nb_of_coefficients,
		const TagType	tag_type = MB_TAG_SPARSE,

		int	verb = -1
	)

Add field on boundary.

Parameters

name	name of the filed

base	approximation base, see FieldApproximationBase
nb_of_coefficients	number of field coefficients
tag_type	type of the tag MB_TAG_DENSE or MB_TAG_SPARSE (DENSE is faster and uses less memory, SPARSE is more flexible if you define field on subdomains)
