Use an Extrusion 1D () or an Extrusion 2D () dataset to extrude data in postprocessing from 1D to 2D and from 2D to 3D, respectively. Using these datasets, you can solve a problem more efficiently in a lower dimension and then extrude it for postprocessing, if the geometry is such that a linear extrusion is suitable.

Use the y minimum and y maximum (for Extrusion 1D nodes) or z minimum and z maximum (for Extrusion 2D nodes) fields to define the range of the extrusion.

The value in the Resolution field is the number of layers added. The default is 10 layers; you must use at least 2.

You define the name of the variable in the extrusion direction in the y variable (for Extrusion 1D nodes) or z variable (for Extrusion 2D nodes) field. For the extrusion datasets, you can use the extrusion variable in the expressions that are being evaluated.

Under Embedding (Extrusion 2D nodes only), specify the extrusion direction using the Map plane to list, where you can choose xy-plane (the default), xz-plane, or yz-plane. Select the Separate levels check box for plotting data for each equidistant point in time, for example.

If needed, specify a value (SI unit: rad/m) in the Out-of-plane wave number field (default: 0). Doing so can be useful when postprocessing solid mechanics models with a specified out-of-plane mode extension.
