Non Systematic Optimization

Setup Non Systematic Optimization.

Non systematic method enables the analyst to setup a 2D free-size topology optimization to highlight the load paths and areas to reinforce. Often, an interpretation to feasible design is required by the design and manufacturing team.

Optimization Deck Setup

Figure 2. Non Systematic Optimization Setup Panel
  1. Select the loadcase from Loadcase Selection and required E-Line from Select E-Line lists.
  2. Choose the Optimization Direction.
  3. Click Load.
    This loads the model, post processing results, selected loadcase and E-Line into the session. HyperView window splits into four:
    • .H3D file of MTRAN analysis, showing selected interface and all 2D Parts.
    • Relative displacement graph for selected interface.
    • Relative Modal Contribution bar chart.
    • .H3D file of Modal Analysis.
  4. Enable the Auto Select checkbox.
    This automatically selects the E-Line interface components from the list. Thickness values are auto filled based on the components selected. You have the option to edit the values.
  5. Optional: Click Components to select components manually from the graphics area.
  6. Optional: Click Review Selection.
    The interface and components in the graphics area are isolated.
  7. Select the required frequency from the Frequency range selection table.
  8. Enable the Auto Fill checkbox.
    This auto fills the Min. (Hz) and Max. (Hz) value fields. If only one frequency is selected, Single Freq. (Hz) is auto filled.

Non Systematic Optimization Options

Loadcase Selection
Lists all the loadcases present in the results file.
Select E-Line
E-Line interface which you want to optimize.
Optimization Direction
Select the optimization direction.
This selection must be based on the information shown in the Relative Displacement or Line Graph.
Components
Components that you want to optimize.
Only 2D PSHELL parts must be selected.
Thickness Values
Minimum and Maximum thickness values.
These are picked from the properties of selected components.
Frequency
Identify frequency(s) to optimize the components for.
Frequency table will be empty for static loadcase.
