Sizing Modes

Sizing can be performed on either a Zone-basis or an Element-basis (for applicable concepts). For Zone-based Sizing, HyperX offers 2 sizing modes: (1) Rapid Sizing and (2) Detailed Sizing. The selection between each mode dictates the optimization methodology used by the software to size designs for the prescribed failure criteria and manufacturing constraints.

The Sizing scheme is selected on the Design Property. For concepts that are supported for element optimization, the first step is to use the dropdown to select between Zone and element Sizing - as indicated by the yellow box in the example. If Zone-based Sizing is selected, the user can select between Rapid and Detailed sizing modes - as shown by the red box in the example image below. These modes differ in both requirements for operation and optimization strategy which are described in each of the sections below.

Tip

Because the Sizing configuration is defined on the Design Property, it is therefore applied to all Zones or Elements (depending on drop-box selection) which reference that design.

Element Optimization

Element Optimization is different from the other two modes in that, as the name implies, it works on individual Elements rather than entire Zones. Using user-defined Material System, fabrication criteria, and ply angle rules (if composite), this algorithm finds the optimal design per Element for the given failure criteria and design loads. As an additional post-processing step, this algorithm will also take into account user-defined blending criteria in order to generate a design that falls in the desired location along the optimization -- manufacturability scale.

Rapid Sizing

In a few seconds, size many FEM Zones to all load cases with different materials and panel concepts. Variable bounds automatically set. Read more in context of the bigger picture here.

Rapid Sizing, as the name suggests, is the quickest optimization algorithm. This mode operates on the Zone-level and only requires that the user define a Material System, fabrication criteria, and ply angle rules (if composite) for the given design concept. It is, therefore, particularly convenient for the earlier stages of the design process, when specific min/max bounds may not be as clearly defined by other design constraints.

Detailed Sizing

In a few minutes, rigorously size many structural Zones to all load cases with different materials for a given panel or beam concept. User controls variable bounds. Read more in context of the bigger picture here.

Detailed Sizing employs a more intuitive, brute-force-type approach to the optimization process. By taking user-defined min bounds, max bounds, step size, and Material System inputs, this algorithm directly generates the design space and systematically evaluates each candidate at each Design Load Case for each failure criteria required. The resulting design is the lightest-weight option that returns all positive margins. This mode also operates on a per-Zone basis for each Zone assigned the Design Property.
