Highlights

Net pressure on both faces of every wall from a compressible-gas SPH run, or a fast screening estimate
Each wall solved as an elastic shell, with dynamic von Mises stress per wall and per thickness
Finds the thinnest wall in the grid that holds, for plain concrete, rebar-mesh concrete or steel sheet

A question it answers

If this tank lets go inside the room, which wall takes the worst load, and is a concrete wall of this thickness enough, with or without a rebar mesh?

What you put in

Tank volume, pressure, temperature and position in the room; room interior size, gap, corridor width, top wall length, wall thickness and height; wall material: concrete (modulus, Poisson ratio, tensile strength, optional rebar mesh) or flat steel sheet (yield strength, safety factor, modulus); optional rebar mesh (bar diameter, spacing, cover, steel yield, concrete compressive strength, cracked-stiffness factor); load source (a fast pressure estimate without a gas run, or a gas resolution: draft, standard, fine). The room is open above.

What you get

The room and tank drawn in 3D, net peak pressure per wall, SPH against shell impulse per wall, dynamic von Mises stress per wall and per thickness, the thinnest thickness that holds the tensile strength (or that none in the grid does), walls coloured by the verdict, and the room as actually analysed.
