Calculation software for the expansion of melon rinds on the top of large tanks
Thread Content
Does anyone among the seniors in the Large Tank Roof Melon Rind Expansion Calculation Software section have it? I’ve been working on large tanks lately, and I don’t know how to calculate the unfolding of melon rinds. Thank you!

Logically, a sphere cannot be unrolled; only approximate methods can be used. 3D software can be employed to achieve this: first, a semi-cylindrical surface with the same diameter as the spherical tank is drawn, and then an isosceles triangle is drawn along a direction perpendicular to the axis of the cylinder. The angle of this triangle depends on the diameter of the spherical tank – 30 degrees, 15 degrees, or 7.5 degrees can all be used. The apex of the triangle points toward the center of the semi-cylindrical surface, and by cutting along the cylinder, an approximate spherical segment is obtained, which can then be flattened.
