Floating Point Exception [Solved]

I'm attempting to do a large deflection analysis using 3DBEAMs yet keep getting a floating point exception. Does anyone know the cause? I've attached my mesh and my comm file. I've searched the web and couldn't find anything relating to it.

It turns out I had used the wrong constitive equation. I should have specified RELATION='ELAS_POUTRE_GR'
