 Like all numerical simulations methods, Scan&Solve™ numerically approximates this idealized model of linear elasticity within some limited precision. As such, Scan&Solve™ can provide insight into structural properties of solid shapes and help in choosing the best available alternative. However, numerical simulation of an idealized mathematical model is not a substitute for physical testing and should not be relied upon for critical design decisions. Like all numerical simulations methods, Scan&Solve™ numerically approximates this idealized model of linear elasticity within some limited precision.

-Scan&Solve computes a [[wiki:sns:sns2014:scan_solve_numerical_model|numerical approximation]] of a mathematical model of [[wiki:sns:sns2014:linear_elasticity|linear elasticity]]. As is the case with all such software, the computed stresses and displacements should not be confused with [[wiki:sns:sns2014:physical_reality|physical reality]] and should not be used for critical design decisions in place of physical experiments. A number of factors, briefly described below, can cause Scan&Solve answers to deviate significantly from physical reality:+Scan&Solve computes a [[#scan_solve_numerical_model|numerical approximation]] of a mathematical model of [[#Mathematical Model:linear_elasticity|linear elasticity]].
