Domain-specific structural workflow is not recommended. New features might not be compatible with this workflow. For help migrating your existing code to the unified finite element workflow, see Migration from Domain-Specific to Unified Workflow.

A StructuralDampingAssignment object contains the damping model and its parameters for a structural analysis model. A StructuralModel container has a vector of StructuralDampingAssignment objects in its DampingModels.StructuralDampingAssignments property.

To set damping parameters for your structural model, use the structuralDamping function.

Properties

Region type, specified as 'Face' for a 2-D region, or 'Cell' for a 3-D region.

Data Types: char

Region ID, specified as a positive integer.

Data Types: double

Damping model type, specified as "proportional", "modal", or "hysteretic".

Data Types: string

Mass proportional damping parameter, specified as a nonnegative number.

Data Types: double

Stiffness proportional damping parameter, specified as a nonnegative number.

Data Types: double

Modal damping ratio, specified as a nonnegative number or a function handle. Use a function handle when each mode has its own damping ratio. The function must accept a vector of natural frequencies as an input argument and return a vector of corresponding damping ratios. It must cover the full frequency range for all modes used for modal solution.

Data Types: double | function_handle
