Hello,

Without seeing how the model was constructed or the data files, it’s difficult to say what is causing this problem. My initial guess would be the local coordinate system of the link source nodes may be misaligned thus giving this strange liner coupling normal stress contour.  
I would suggest sending your model to [FLAC3Dsupport@itascacg.com](mailto:FLAC3Dsupport@itascacg.com) if you wish to do so.

Thanks,  
Derrick
