-Scan&Solve computes a [[#scan_solve_numerical_model|numerical approximation]] of a mathematical model of [[#linear_elasticity|linear elasticity]]. As is the case with all such software, the computed stresses and displacements should not be confused with [[#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:

   * **Model is not linear elastic.** A linear elastic model of stress is not applicable in many situations, e.g. non-linear material properties, large plastic deformations, vibrations, buckling, thermal stresses, and so on.
