Detailed Description

Constructor & Destructor Documentation

◆ XfemFracture() [1/2]

XfemFracture::XfemFracture	(	int	npoints,
		int	ndim,
		double *	coordinates,
		const QString &	fracType = `QString("HydraFrac")`,
		const QString &	fracState = `QString("Open")`
	)

Constructor for a fracture definition based on a set of points defining its geometry.

Gets as parameters the number of points in the fracture geometry definition, the point dimension and a vector with the point coordinates. The vector size should be equal to nnodes * ndim and the coordinates should be organized inside per point (ex: x1, y1, x2, y2, ..., xn, yn).

IMPORTANT: The fracture takes ownership of the given data vector and will destroy it on its destructor.
