     * The model is physically unstable, and small changes in the geometry, material, or boundary conditions lead to large changes in displacements and/or stresses. Numerical approximation may simulate such small changes during the solution process.     * The model is physically unstable, and small changes in the geometry, material, or boundary conditions lead to large changes in displacements and/or stresses. Numerical approximation may simulate such small changes during the solution process.
   * Are converged solutions always correct? No. Every numerical procedure has its limitations, and Scan&Solve™ is no exception. The correctness of computed results depends on specific elements used in the solution procedure and individual steps in the procedure process, including function and solid sampling, surface and volume integration, and the solution of linear system of equations. To validate the solution procedure, it is highly advised to test it against a variety of similar and different problems, as well as on problems with known solutions.   * Are converged solutions always correct?
