Workflow for Performing 2D Simplification You select from the available plane stress, plane strain, extruded, or axisymmetric options. After selecting a 2D simplification assumption, the workflow for solving the problem is similar for all options. Contents Defining a 2D Simplification Study You use the 2D simplification option when defining a static, nonlinear, thermal, pressure vessel design, and design studies on qualifying 3D models. 2D Simplification PropertyManager The 2D Simplification PropertyManager manages the creation of 2D sections from 3D geometries. Creating the 2D Section You select the type of 2D simplification option to use, create a 2D section, and define the section depth or the axis of symmetry. Viewing Results After running a 2D simplification study, you can plot the results in 3D. Examples of Simplification Options Study Tree Features Restrictions on 2D Simplification Studies Setting up a 2D simplification analysis is similar to setting up any other study.
