1.	input_file output_file

-version

Reads .res files into HyperGraph 2D (including those with multiple steps) that were created in HyperMesh.

Files with single and multiple steps.

Converts .res files into .bin files that are readable by HyperGraph 2D.

Usage

To run hmread at the command prompt:

hmread input_file output_file

hmread -version gives the version, build date, and build time.

Reads ADAMS spline data (usually in the form of an .adm file) into HyperGraph 2D. This reader does not translate files.

The Abaqus ODB reader in HyperView and HyperGraph 2D reads both field and history results from the Abaqus ODB file. The history result names are post fixed with (Time History). Results without this post fix are field data. Time history results have two components (or columns): Time and Value.

The Time component is the first column of the result. The value can be time steps, frequency, or mode number, depending on the analysis types.

The Value component is the actual value for the result type.

Note	Time data for different result types can be different. It is recommended to use both the Time and Value from the same result type.

How do I...

1.	Select the Build Plots icon, , from the toolbar.

2.	Select the same result type and request for both the X and Y data.

3.	Select Time as the X Component.

4.	Select Value as the Y Component.

The Value component is the actual value for the result type.

5.	Click Apply.

In HyperGraph 2D, displacement, acceleration, force, and velocity are supported. Stress and strain are not supported.

NASTRAN centroidal results in HyperView: With the Average color option on, HyperView averages element values to nodes to create a smooth contour plot. You can query elements for centroidal values, but not averaged values, at nodes. With the Average color option on or off, the contour plot reflects exactly what is in the results file.

NASTRAN corner results in HyperView: When using the Display contour data option to create a contour plot, HyperView uses a simple average at nodes. The legend reflects corner results. You can query elements for node values, but you cannot query calculated average values. When you are not using the Display corner data option to create a contour plot, HyperView uses the element values in the results file.

Supports stress, strain, and force for CELAS, CROD, CBAR, and CBEAM.

5 Supports 1D elements (CBUSH, CELAS, CDAMP) forces in SOL 108/111.
