When you use Tekla Structural Designer to model, analyze, and design structures, you will become familiar with the following concepts:

A structural model is a 3D model that includes the physical members/objects you create using Tekla Structural Designer, and information related to them. Each member/object in the physical model will exist in the completed structure.

The structural model also contains information about the loadcases and combinations that act on the physical members/objects.

A solver model is a 3D model that is created from the structural model. It is used for analyzing structural behavior, and for design.

When you create a solver model, Tekla Structural Designer generates the following analysis objects and includes them in the solver model:

• Solver nodes
• Support conditions for nodes
• 1D solver elements
• 2D solver elements
