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


Reference calculation
-------------------

This calculation is a non-regression test. It therefore does not present reference results.

Calculation process:


* Calculation of stiffness and mass matrices (operator ASSEMBLAGE),


* Calculation of seismic loading,


* Direct non-linear transient analysis in relative coordinate system, in mono-support.


Reference sizes
--------------------

:math:`\mathit{DX}`: represents, depending on the size field:


* DEPL: the component of the relative displacement along the :math:`x` axis


* REAC_NODA: the component of the nodal reaction along the :math:`x` axis

:math:`\mathit{V1}`: component of the VARI_ELNO field giving the cumulative plastic deformation.
