Benchmark solution ===================== Calculation method used for the reference solution -------------------------------------------------------- The membrane-type calculation with the non-eccentric plate is used as a reference. The non-regression with respect to the results obtained by this first calculation is verified. Benchmark results ---------------------- They consist of the values of the displacement field :math:`\mathrm{DX},\mathrm{DY},\mathrm{DZ},\mathrm{DRX},\mathrm{DRY}` at the nodes :math:`\mathrm{N66}` (for the DKT) and at the nodes :math:`\mathrm{N1}` (for the DKQ) and the calculation of the frequencies of the first 4 modes. Uncertainty about the solution ---------------------------- The uncertainty is zero since it is the same calculation carried out by two different methods.
