Finite element codes describe "bricks", tetrahedra, quadrilaterals with midside vertices etc. These predefine a vertex order, and then list the nodes for each connected group. Thus for ANSYS or abaqus you'd defined a linear (trilinear, actually) brick using a list of 8 vertexes in a particular order. CalculiX is an open source FEA code. In the theory section in this document describes node order for the hexahedra.
