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.

Modelings D_PLAN_HM, D_PLAN_HHM, D_PLAN_THM, D_PLAN_THH, D_PLAN_THHM, AXIS_HM,
AXIS_HHM, AXIS_THM, AXIS_THH, AXIS_THHM, (Phenomenon: MECANIQUE) correspond to elements
stop whose meshs supports are surface.

1 Discretization

1.1
Degrees of freedom

DX, DY indicate the degrees of freedom of displacement.
PRE1 and PRE2 indicate two degrees of freedom of pressure, whose precise significance depends on
laws of behavior used. TEMP indicates the temperature.

Net support of the matrices of rigidity

The meshs support of the finite elements can be tetrahedrons, pyramids, prisms or
hexahedrons. The elements are isoparametric.
