Structural analysis

---

1D analysis does not require geometry from CAD software. Such structures are defined element-by-element within Onsimulation.

• Truss-like structures
• Frame-like structures

2D analysis requires geometry that is defined using a single extrude or revolve. A planar face of the solid is selected to specify the plane on which the analysis is to be performed. The types of 2D analysis are:

• Plane stress
• Plane strain
• Axisymmetric

Thin structures made of sheet metals or thin plastic shells must be modeled as plates or shells. The geometry for such models should be a surface or a face of a solid.

• Plate-like structures
• Shell-like structures

If a structure cannot be modeled as 1D, 2D, plate or shell then it must be modeled as 3D. The geometry can be any solid model created in CAD software.

• Example 1
• Example 2

Assembly models can be 2D or 3D and is typically used to model the interaction of multiple parts often with parts made of different materials.

• Tied Contact
• Sliding Contact
