Hi Aleks,<div><br></div><div>Thanks for the tip. Unfortunately, fixing the handedness did not make the free-slip case work for me. When you were simulating an annular cylinder, did you ever have the SYM BC's on both the sides and the ends?</div>
<div><br></div><div>I think I've determined that neither the Pn/Pn-2 method nor the stress formulation is the problem with my 3D annular cylinder. I conclude this because the simulation runs properly with IFSTRS=T when the sides are SYM and ends are W, or when the sides are W and the ends are SYM. It is only when both sides and ends are SYM that the simulation doesn't work. Any thoughts?</div>

<br>
I was using a similar transformation for the annulus except for the order of r & theta, i.e. I mapped [r,theta,z] -> [x,y,z] preserving right-handed coordinate system...<br>
