How to make a bent line type Main steps Define a line type built up using a number of segments. The number of segment must be fine enough to describe the curvature/bent shape you want. The location of nodes in a segment is calculated using linear interpolation (located on a straight line between the segment ends) Create two super nodes. The distance between the two super nodes is the length of the line type In the section where the line type is defined you can define the bent shape in the complete description 1. Example: bend the line type in local z-direction The stippled line is the bent shape Find the z-offset at each end of the segments. The offset is added at end 2 of the segment The last segment has no offset Run static analysis and view the bent line type How to import kinematics from a file How to model a regular wave using irregular wave input
