Summary:
This document describes for modelings
D_PLAN
and
AXIS
into thermo_hydro_mecanic:
·
degrees of freedom carried by the finite elements which support modeling,
·
the related meshs supports,
·
supported materials and loadings,
·
options of calculations for the elementary matrices and the post processing,
·
nonlinear possibilities as well as the options of the breaking process if they exist.
