fracture.normal

Syntax

Vector Access

norm = fracture.normal(frac<,icomp>)

fracture.normal(frac<,icomp>) = norm

Get/set the fracture normal.

Note

• The fracture must fall completely within the model domain.
• The sign of the normal is inverted if the {$y$-component in 2D; $z$-component, in 3D} is less than 0.
• The provided normal is normalized (i.e., norm / | norm |).

Returns:

norm - normal vector or component

Accepts:

norm - normal vector or component

Arguments:

frac - fracture pointer

icomp - optional vector component

Component Access

fnorm = fracture.normal.x(frac)

fracture.normal.x(frac) = fnorm

Get/set the $x$-component of the fracture normal.

Note

• The fracture must fall completely within the model domain.
• The sign of the normal is inverted if the {$y$-component in 2D; $z$-component in 3D} is less than 0.
• The provided normal is normalized.

Returns:fnorm - $x$-component of the fracture normal Accepts:fnorm - $x$-component of the fracture normal Arguments:frac - fracture pointer

fnorm = fracture.normal.y(frac)

fracture.normal.y(frac) = fnorm

Get/set the $y$-component of the fracture normal.

Note

• The fracture must fall completely within the model domain.
• The sign of the normal is inverted if the {$y$-component in 2D; $z$-component in 3D} is less than 0.
• The provided normal is normalized.

Returns:fnorm - $y$-component of the fracture normal Accepts:fnorm - $y$-component of the fracture normal Arguments:frac - fracture pointer

fnorm = fracture.normal.z(frac) (3D only)

fracture.normal.z(frac) = fnorm

Get/set the $z$-component of the fracture normal.

Note

• The fracture must fall completely within the model domain.
• The sign of the normal is inverted if the $y$-component ($z$-component; in 3D) is less than 0.
• The provided normal is normalized.

Returns:fnorm - $z$-component of the fracture normal Accepts:fnorm - $z$-component of the fracture normal Arguments:frac - fracture pointer
