Hi Stephan,<br><br>I see, thanks. I can`t find any documentation about cyclic BC`s. What is their symbol for the box file? Also, I don`t see a logical switch for IFCYCLIC. Do I just add another line?<br><br>Also, I have stress-free BC on curved boundaries. A series of error messages led me to believe that I had to use the stress formulation, and that this required me to use Pn/Pn-2. Is this not the case?<br>
<br>Best,<br><br>David<br>
