Tip
See Sizing vs Analysis for recent updates to the Sizing and Analysis workflows.
To Size in HyperX is to find the optimum cross-section, dimensions, and Material System that minimizes the weight of the Structure while satisfying all specified requirements including: positive margins of safety for specified failure criteria, variable bounds, manufacturing considerations, etc.

HyperX’s interactive optimization approach facilitates the user to start with an open design space with millions of candidates and funnel down to a preferred design. Read more here.
Sizing is one of the two different inputs that can be defined on the Design Property. Define sizing inputs by first selecting a Sizing Mode and then providing the corresponding design space information for each variable. HyperX offers a Sizing Mode suitable to each stage in the design process - from early-stage DOE through to more specified Sizing requirements as certification and part release draw near.
The Sizing operation is executed for a selection of Zones by clicking the Size icon on the Run tab of the Ribbon
Important
This operation will only take into consideration the Sizing Inputs from the Design Property (not the Analysis Inputs).
Use the Sizing Overrides table to enforce engineering judgment to further refine Sizing results - without changing the overall Design Property.
The click-by-click steps for setting up and Sizing a particular Entity vary depending on the Entity. See:
-
Composites - There is extensive capability in the realm of Composite Laminate Optimization
-
Size with specially-optimized Laminate Families or unrelated discretized Laminate Candidates
-
Automatically Size and generate weight vs. producibility relationships as a pareto frontier for a selection of Laminate Families or ply angles, using the automated Design Study tool.

-
Section Cuts - There are also workflows that employ Section Cut entities, such as sizing for Section Cut Stiffness Requirements
-
FEA Iteration - Sizing changes the global stiffness of the part, thereby altering the load path. Capture this effect, as well as implement global stiffness constraint with HyperFEA - automatic FEA iteration.
