Composite flex blody stress/strain results

Hello,
 
I am simulating a composite material truss in Adams. For some reason, while the deformations are very small the strains are huge in the post processor (e.g. the max deformation at one of the truss' s rods is <0.1 mm but the strains are >10^29.
 
How does Adams calculate stresses and strains for composite flex bodies? Do I perhaps need to change my settings when generating the mnf fine for the flexible bodies? I am attatching the header of the SOL103 for the mnf file below.
 
Thanks,
 
Josef
