Create 1D Bolt Pretension
Description
User can model the pre tension in the tightened bolt in several ways. The tension in the tightened bolt is modelled by creating RBEs, Bars and force. This is called bar pretension. This dialog box shows the different options to create the bar pretension as pictures.
Types of Bar Pretension
Through
Two RBEs will be created. One is on the top of the head and the other is on the bottom of the thread and these are connected by n number of bar elements. Nodes connected to the top and bottom RBEs are within the diameter (diameter of edge * Scale). Pretension force will be applied on the mid point of the master nodes of top and bottom RBEs. This node also can be constrained by selecting the lock option.

RBEs will be created based on the option. Depth "D" is the distance from top edge of the thread to the master node of bottom RBE. Half of the Pitch "P" value above and below the master node will be considered for including the nodes on the cylindrical face to the bottom thread RBE.
