This element is named after Ed Fuller, who suggested it^{4.2}. It is an element which is
isotropic in its elastic coefficients, but is orthorhombic in its
thermal expansion coefficients. It can be used to simulate
transformation strains or residual stresses where the elastic
coefficients are not known precisely, but the expansions are known not
to be isotropic.
Parameters
 elastic coefficients
 The elastic coefficients young and poisson have the same
meaning as they do in the isotropic element (Section
4.5.1. [stress]
 thermal expansion coefficients
 The thermal expansion coefficients a1, a2, and a3 are the
diagonal components of the thermal expansion tensor .
^{4.3} [inverse temperature]
 orientation
 Without rotation, the thermal expansion coefficient a1 governs
expansion in the direction, a2 in the direction, and
a3 in the direction (out of the screen). See Section
4.3. [degrees]
