Hi James,
from the manual I got what the shell orientation is used for. For our case, I forgot to mention: we use Orthogrid panels.
Assuming a consistent shell orientation within each component: Am I right that with, say, a shell orientation in the circumferential direction of my cylindrical fuselage, the 0deg-results (stiffener spacing, height, etc) are valid for the circumferential direction (and the 90deg-results for the cylinder axis direction)? So the sizing was not wrong, I just have to remember this when plotting 0deg- and 90deg-results because the "labeling" is wrong? This information would help me to decide if current results can be used or have to be thrown away...
Besides that: I understand that varying shell orientations within assemblies (and particularly within components) is highly critical. I will change that.
Thanks,
Jan
