I Want to Mesh Chest and Lap Belts Using Two Different Element Properties

If you define the whole belt, chest and lap, in one operation then it will only be possible to mesh it using a single property. Also the nodes at fixed point locations, eg sliprings, will be common to their adjacent segments giving continuity across sliprings.

To get separate properties it will be necessary to create two separate belt definitions: one for the chest section and one for the lap. These will then be able to have different properties defined during their meshing operations.

By default this will give separate nodes at end points, thus losing the continuity of the belt through sliprings. However the MESHING operation permits you to stipulate the end nodes to be used, so if continuity is required the second section to be meshed can still be made to join up with the end of the first one.

There is no limit to the number of belt definitions that can be defined in a model, and they may be joined up as required.

This example shows how a simple four-point harness could be generated using four separate belt definitions: left and right sides, upper and lower cross-sections. Two different section properties are used.
