# New Model Wizard : Structure

This page sets up the basic details of the structure. Cancelling at any time will result in no new document.

# Definition

Structure Type

The structure type describes the type of structural model to be considered. The options are

  • Space – 3D structure type. This is the most general structure type, and all the other can be considered as subsets of this.
  • Plane stress – 2D analysis option with plane stress conditions.
  • Plane strain – 2D analysis option with plane strain conditions.
  • Axisymmetric – 2D analysis option with axisymmetric conditions.

Previous versions of GSA offered ‘Plane’ and ‘Grid’ structure types. These have been removed as structure types but the same conditions can be achieved with a Space structure and setting the appropriate global restraints.

Units

Opens the Units dialog to allow the user to set a default set of units for the structure. The current units are reported on the page.

Grid Data

Grid lines and grid planes can be assigned to give a framework for subsequent model generation.
