**v1.01.166** ZZZZ166 - Calculation of heat flow
====================================================

**Summary:**

The purpose of this test is to validate the thermal flow calculation options: FLUX_ELGA and FLUX_ELNO.

In addition, due to the use of a unit thermal conductivity, this test is also used to validate the calculation of the temperature gradient. In fact, in this case the gradient is equal to the opposite of the flow.

The 6 models tested are:


* A In 2D PLAN: triangles of degree 1, quadrangles of degrees 1 and 2 and quadrangles with 9 knots,


* B In 2D PLAN_DIAG: triangles of degrees 1 and 2, quadrangles of degrees 1 and quadrangles with 9 knots,


* C In 2D AXIS: triangles of degree 1, quadrangles of degrees 1 and 2, and quadrangles with 9 knots,


* D In 2D AXIS_DIAG: triangles of degrees 1 and 2, quadrangles of degrees 1 and quadrangles with 9 knots,


* E In 3D: hexahedra, pentahedra, pyramids and tetrahedra of degrees 1 and 2, hexahedra with 27 knots,


* F In 3D_ DIAG: hexahedra, pentahedra, pyramids, and degree 1 tetrahedra.
