Benchmark solution
=====================


Calculation method used for the reference solution
--------------------------------------------------------

Comparison of the results with those obtained using CASTEM 2000 (modeling A (3D) (3D) (modeling A (3D): single-support combination CQC, multi-support excitation identical to combination supports CQC);

Otherwise, validation consists of:


* find the single-support response using the multi-support path, in the case of excitations identical to the supports (models A (3D) and B (:math:`\mathrm{2D}`), combination CQC);


* check the non-regression of the response in the case where there is no reference data (A and B models, different excitations at the supports).
