Anisotropic Material Orientation and USERAN subroutine

[YoungTurk]

I'm trying to do analysis of an anisotropic 3D solid using Solid64 elements. The problem is, I need to orient the material differently in different parts of the solid. According to the documentation, I should use the USERAN subroutine to orient the element coordinate systems which define the material orientation.

I consulted the "Guide to User Programmable Features" and it says you can call subroutines, including USERAN, with the USRCAL command. When I try this, ANSYS tells me USERAN is not an available function.

So, does anybody know how I can access USERAN or otherwise orient my material properties?

Solved my problem in this way. Created local coord systems with the LOCAL command and then called the coordinate system with ESYS before meshing each volume. Its a slow and tedious procedure, but I figured I'd post it here for futur reference. Never did get the USERAN routine to work.
