Unformatted text preview: d PLANE42 elements. The air
gap is modeled with 2-D tri-shaped TRANS109 elements with KEYOPT(1) = 1 for area weighted morphing. NodeNode contact is modeled in the air gap using CONTAC12 elements. The beam is constrained in the X and Y directions on the left side and is free only in the Y-direction along the span. The beam is suspended 0.7 µm over
the ground plane with a contact stop at 0.1µm. Results Comparison
