Hi,Based on the second image, it looks like the aligner has a different curvature than the teeth and that is the reason, the two are not in contact completely. Could you share a snapshot showing how the displacement of 0.25mm was applied (I can't make out the y-axis in this image)? Also, are you not getting contact pressure results in the region where contact has been established (on the left and right ends in image 2)? If so, can you share a snapshot showing how the contact and target sides are defined?Thanks,Sai
