Eigenvalue extraction for unconstrained patches of elements

This problem contains basic test cases for one or more Abaqus elements and features.

Continuum elements

Elements tested

Continuum elements (excluding coupled temperature-displacement and pore pressure elements).

Problem description

The models consist of the same patches of elements used in the tests defined in Patch tests. The first step consists of an eigenvalue analysis of the model with no boundary conditions. The second step applies a uniform pressure load on all four edges and sets the NLGEOM parameter. The third step performs an eigenvalue analysis of the prestressed model with no boundary conditions. Results are printed only for the first and third steps.
