Design sensitivity analysis controls

Features tested

This section includes various tests used to verify the behavior of the DSA controls. Output variables, unsupported elements, and restart are also verified.

Problem description

Elements are subjected to concentrated or distributed loads. Static analyses are performed.

Results and discussion

The response sensitivities are verified by comparison to overall finite difference results.
