Matrix Browser

Use the Matrix Browser to explore the HyperMesh and HyperView data entities and export the entities to external files for further analysis.

From the Post ribbon, click the Matrix tool.
Figure 1.


The Matrix Browser is organized into two main sections. The top half of the browser provides a table view similar to an Excel spreadsheet. The bottom half of the browser shows and allows you to browse the HyperMesh/HyperView (data source) and its data entity (object) names and their data names (attributes). The HyperMesh database entities are shown in green and the HyperView database entities are shown in yellow. When you select a column in the table it becomes an active column and is highlighted in blue. All of the following searches are conducted on the active column.
Figure 2.


Matrix Browser Functionalities

Below is a highlight of the functionalities supported by the Matrix Browser.
  • Query and modify HyperMesh and HyperView data entities without writing cumbersome Tcl coding.
  • Export HyperMesh and HyperView data to an Excel file for further post-processing and report generation.
  • Establish a link between HyperMesh and HyperView in order to access model data, such as material, property, beam section, and results data in a single environment. The browser supports the selection of multiple load cases from the HyperView results database.
  • Create new procedures (macros) to enable automation with minimum Tcl coding and also capture the automation process as Tcl scripts. These macros can be used external to the Matrix Browser, like the tools in the Altair script exchange.
Note: The Matrix Browser does not allow for the creation of new HyperMesh entities. The tool queries and modifies existing entity data. The browser also does not allow extensive geometry (lines, surface, solids) data query. It is intended for FE data and results that are already in the HyperMesh/HyperView databases.

Prepare to Use the Matrix Browser

  1. Open an existing HyperMesh model or import solver data.
  2. Use the split screen and invoke HyperView.
  3. Load the results file for the solved data into HyperMesh.
  4. From the Post ribbon, click the Matrix tool.
    Figure 3.


    Figure 4. . Model opened in HyperMesh and HyperView.


    Note: HyperView is only needed if the results are accessed from the Matrix Browser.

Access HyperMesh Data Using the Matrix Browser

  1. In the DataSource column, select HMdata.
  2. In the Entities column, select a HyperMesh entity.
  3. Click Query.
  4. In the panel area, use the entity selector to select HyperMesh entities to add to the matrix.
    A new green colored column is added to the matrix.
  5. In the matrix, click the elements header to access entity data.
    The elements column turns blue when clicked, indicating the entities are active for the search operation. The Datanames column is populated with entity attributes from the HyperMesh database for the element IDs shown in the elements column.
    Figure 5.


  6. Select the material, property, or any other attribute(s) and click Query.
    One of more columns will be added. If you selected material, the material IDs will be shown.
    Component attributes you can select include:
    • Masses.
    • Center of gravity (CoG) coordinate, X, Y, or Z.
    • Moments of inertia components expressed from the origin (IXX, IYY, IZZ, and so on).
    • Moments of inertia components expressed from the component CoG (IXXcog, IYYcog, IZZcog, and so on.
    Figure 6.


  7. The next step is to get E, Nu from the material. Activate the material column, and then select E and Nu from the data names.
    Figure 7.


  8. Click Query.
  9. Repeat this process for property and get the element thickness.
Derived data is not stored in HyperMesh data. It is calculated by a procedure predefined by the Matrix Browser to calculate useful data from HyperMesh data. You can create these Tcl procedures and store them in the Matrix start up. They will show up in the browser as derived_datanames. The pre-installed derived_datanames are width, height, radius and adjacent.

Access HyperView Results From the HyperMesh Database
