Solid Stress Normal Modes Solver Properties

Algorithm (read only)

Specifies the algorithm used for the eigenvalue solver. Currently only the Krylov-Schur algorithm is available.

Model Compatibility

Allows you to select whether the model compatibility is enforced. The options for this are:

Enforce—stops the normal mode analysis if the simulation contains incompatible settings such as:
- The Rayleigh Damping model
- The Gravity model
- Segment loads
- Thermal models within a linear setup
- FSI interfaces within a linear setup
Ignore— allows the normal modes analysis to run to completion when incompatible settings are present within the simulation. The final normal mode analysis may be inaccurate depending on the incompatibilities.

Convergence Tolerance: Specifies the convergence for the eigenvalue solver.
Iterations: Specifies the maximum number of iterations required to converge the eigenvalue problem.

Smallest/Largest

Allows you to select the range of eigenmodes extracted from the solution. The options are:

Smallest—allows you to extract the lowest eigenmodes from the eigenvalue problem.
Largest—allows you to extract the highest eigenmodes from the eigenvalue problem

Number of frequencies

Specifies the desired number of eigenmodes to be extracted from the solution.

Extracted (read only): Specifies extracted data sets present within the normal modes results table.

Modal Displacement: Vector field function that describes the modal displacement. For more information, see Normal Modes

Perform Normal Modes Analysis: Executes the normal mode analysis for the specified properties.
New Normal Mode View: Creates a Normal Mode View under Solution Views. For more information, see Normal Modes View Reference.

Export...: Allows you to save the normal modes solution data to a .csv file.
Extract: Allows you to extract the Mode, Frequency, and Eigen Value data from the normal modes solution.
Tabulate...: Allows you to visualize the normal modes solution data in a table within Simcenter STAR-CCM+.
