HyperGraph Interface with OptiStruct

This section explains how HyperGraph interfaces with the OptiStruct solver.

For information on hgopt, refer to External Readers.

The HyperGraph reader supports the OptiStruct OPTI(ASCII) format.

The figure below compares the old and new OPTI formats using ELFORCE (.force) as an example, which has improved readability.



Figure 1.
The tables below summarize the result and analysis types that support the OPTI format.
