COMPUTE EIGEN-VALUES OF A SYMMETRIC 3X3 MATRIX. ONLY 6 COMPONENTS ARE NEEDED.¶
Computes the three eigenvalues of a symmetric 3×3 matrix whose six independent components are supplied as time-history curves. Use this worker whenever you need the principal values of a stress, strain, or inertia tensor at every time step.

Inputs¶
| Label | ID | Type | Default | Required | Description |
|---|---|---|---|---|---|
| Curves | curves | vector | — | Vector of time-history curves representing the six independent components of the symmetric 3×3 matrix (e.g., S11, S22, S33, S12, S13, S23 for a stress tensor); supply exactly 6 component curves in consistent units. |
Outputs¶
| Label | ID | Type | Description |
|---|---|---|---|
| curves_eigen_values_output_1 | curves_eigen_values_output_1 | vector | Vector of three time-history curves containing the three eigenvalues (principal values) of the input symmetric 3×3 matrix at each time step, ordered from smallest to largest. |
