2D Simplification

You can simplify certain 3D models by simulating them in 2D. 2D simplification is available for static, nonlinear, pressure vessel design, thermal studies, and design studies. You can save analysis time by using the 2D simplification option for applicable models. 2D models require fewer mesh elements and less complex contact conditions compared to the 3D models. After running the analysis, you can plot the results in 3D.

You can select from four types of 2D simplification options.

Plane Stress

Requires one of the dimensions of the model to be much smaller than the other two. For such problems, one of the principal stresses is neglected to make the stress state two-dimensional.This option is not valid for thermal studies.

The figure shows an example of a bracket under distributed load.

Plane Strain

Requires one of the dimensions of the model to be much larger than the other two. For such problems, the deformation along one of the dimensions is neglected and the strain state is two-dimensional. This option is not valid for thermal studies.

The figure shows an example of a dam under water pressure.

Extruded

Models problems with constant thermal loads along the extrusion direction. This option is available only for thermal studies.

The figure shows an example of a long block at a uniform temperature suddenly exposed to a convection environment.

Axisymmetric

Models geometries, material properties, loads, and fixtures that have a rotational symmetry about an axis.

The figure shows an example of an o-ring pressed into the groove by a top plate. For this example, you can model any cross section about the axis of revolution.

The figure shows another example of a hollow cylinder insulated at the inner surface and exposed to a convection environment on the outer surface.
