OptiStruct Results Supported by HyperView

HyperView supports results from OptiStruct 8.0 and earlier versions.

HyperView can read model and results data from several OptiStruct input and result file formats as shown in the following table:

File Format (file extension)

Model Data

 Results Data

OptiStruct input file (.fem)

YES

NO

Hyper3D (.h3d)

YES

YES

HyperMesh (.res)

NO

YES

Output2 (.op2) *

YES

YES

* For more details about the HyperView support of the Output2 format, see Supported Nastran Results in HyperView.

Results are read into HyperView either as scalars, vectors or tensors.  This is indicated by a character that appears in parenthesis after the result type: (s) for scalar, (v) for vector and (t) for tensor.  All results types may be selected in the contour and iso-value panels, only tensor results may be selected in the tensor panel, and only vector results may be selected in the vectors panel.

Complex results are indicated in a similar manner: (c) or (comp) indicate complex results, (real) indicates the real part of a complex result, (imag) indicates the imaginary part of a complex result, (magn) indicates the magnitude part of a complex result and (phas) indicates the phase part of a complex result.

In HyperView you can transform tensor and vector results to different coordinate systems following certain system projection rules.  You also can calculate average certain results using various averaging schemes.  For more information about how transformation and averaging are handled in HyperView, see:

Note:

For shell element tensor results written to the Hyper3D (.h3d) or Output2 (.op2) format, what HyperView refers to as the “analysis system” is the “element system” and not the actual analysis system, in which the HyperMesh format (.res) results are output.

The following table indicates how OptiStruct analysis results from the Hyper3D and HyperMesh formats are handled by HyperView.

** Scalar results may be obtained by specifying DIRECT in the type field on the relevant OptiStruct output request.

*** These are scalar for complex results.
