D modeling
==============


Characteristics of modeling
-----------------------------------

This modeling is identical to modeling A, the only difference is in the solver used: MUMPS is used here.


Characteristics of the mesh
----------------------------

Number of knots: 10

Number of meshes and types: 9 SEG2


Tested sizes and results
------------------------------

As for modeling A, we test on the real and imaginary parts of the :math:`\mathrm{DX}` component of the displacement, speed and acceleration of point :math:`{P}_{4}`. The results are equal to those obtained with modeling A, up to at least one decimal place inclusive.
