9. Operands for thermal options

9.1. Operand THERMIQUE

| 'FLUX_ELGA'
| 'FLUX_ELNO'
| 'NODE_FLOW'

Calculation of heat fluxes from temperature.

List of field components:

FLUX FLUY FLUZ	Heat flow in the three directions of space (in the middle sheet for shells)
Additional components for the shells:
FLUX_INF FLUY_INF FLUZ_INF	Heat flow in the three directions of space in the lower skin
FLUX_INF FLUY_INF FLUZ_INF	Heat flow in the three directions of space in the upper skin

| 'GRAT_ELGA'
| 'THANK_ELNO'
| 'THANK_NOEU'

Calculation of temperature gradients.

List of field components:

GRAT_X GRAT_Y GRAT_Z

Temperature gradient in the three directions of space

| 'HYDR_NODE'

Hydration calculation.

List of field components:

HYDR

Hydration

note

The field “HYDR_ELNO” is calculated natively by the non-linear thermal operator THER_NON_LINE for modeling concrete [R7.01.12].

| 'SOUR_ELGA'

Calculation of a heat source.

List of field components:

SOUR	Heat source

This source is calculated from an electrical potential via Ohm’s law. This electrical potential must have been calculated by the operator THER_LINEAIRE [U4.54.01] by making the necessary analogies. This source can then be used in a thermal calculation via the SOUR_CALCULEE keyword of the AFFE_CHAR_THER [U4.44.02] command.

| 'ETHE_ELEM'

Calculation of thermal energy at equilibrium from the temperature field \(T\).

List of field components:

TOTALE

Thermal energy
