Anisotropy Matrix coefficients

DESCRIPTION

Through sub-models,  Polyflow allows the user to add a conductive contribution to the energy equation,  either in dimension 0 (point), 1 (line) 2 (surface) or 3 (volume).  The dimension is linked to the dimension on which the sub-model is being defined.

For all cases,  the material can either be isotropic or not.  When it is isotropic,  one must enter the volumetric conductivity and the anisotropy matrix is the unit matrix.
To make the material non-isotropic,  enter the cartesian coefficients of the anisotropy matrix,  that will be multiplied by the thermal conductivity (so that it is non-dimensional).

Note that because of physical reasons the anisotropy matrix must be positive-definite.
