SEURBNUK-2 is a two-dimensional, axisymmetric, eulerian, finite difference containment code. The numerical procedure adopted to solve hydrodynamic equations is based on the semi-implicit ICE method (itself an extension of the MAC algorithm). SEURBNUK has a full thin shell treatment for tanks of arbitrary shape and includes the effects of fluid compressibility; it accommodates fluid flow through porous media and porous structures; it solves the thin shell equations quite separately from those of the fluid, with the time step for the fluid flow calculation an integer multiple of that for calculating the shell motion. The code is limited to dealing with a single fluid, the coolant, whereas the bubble and the cover gas are treated as cavities of uniform pressure calculated via appropriate pressure - volume - energy relationships. This manual describes the input data specifications needed for the execution of SEURBNUK-2 calculations and nine sample problems highlight the code capabilities. Information is included to aid those unfamiliar with SEURBNUK-2.
