Constructs a zed section.

Constructs a zed section with the bottom left corner at the origin (0, 0), with depth``*d``, left flange width b_l, right flange width b_r, lip l, thickness t and outer radius r_out, using n_r points to construct the radius. If the outer radius is less than the thickness of the Zed Section, the inner radius is set to zero.

Parameters:

• d (float) – Depth of the zed section

• b_l (float) – Left flange width of the zed section

• b_r (float) – Right flange width of the zed section

• l (float) – Lip of the zed section (which can be zero)

• t (float) – Thickness of the zed section

• r_out (float) – Outer radius of the zed section

• n_r (int) – Number of points discretising the outer radius

• material (Material) – Material to associate with this geometry

Returns:

Zed section geometry

Return type:

Geometry

Example

The following example creates a zed section with a depth of 100 mm, a left flange width of 40 mm, a right flange width of 50 mm, a lip of 20 mm, a thickness of 1.2 mm and an outer radius of 5 mm, using 8 points to discretise the radius:

    d=100, b_l=40, b_r=50, l=20, t=1.2, r_out=5, n_r=8
