mesh.Mesh.area#

Mesh.area()#

Return the total area of a Mesh.

Returns#

float: For a level 2 Mesh, the sum of all element areas(); for a level 3 Mesh, the area of the border_mesh(); 0.0 if areas() returned None.

Examples#

>>> Mesh(eltype='quad4').subdivide(3,2).area()
1.0

For a level 3 Mesh, note the difference between these three: the area of the border, the area of all faces (includes non-border faces), the sum of all element face areas (includes faces multiple times).

>>> M = Mesh(eltype='hex8').subdivide(4,3,2)
>>> M.area(), M.face_mesh().area(), M.areas().sum()
(6.0..., 12.0..., 18.0...)
