Modal solution options (Simcenter Samcef)

To set up solver options for a Modal Analysis solution, you can:

• Define the number of eigenvalues and the frequency range to compute.

• Define the Default Reference Temperature (.GEL TEMP). For more information, see Reference and Initial Temperatures in Samcef (Simcenter Samcef).

• Define Prolog and Epilog text. For more information, see Customizing a Simcenter Samcef input file with user defined text.

• Specify Output Requests. For more information, see Samcef output requests.

• Specify the Effective Masses Option and related options.

• Specify the Solver Type algorithm to use, or select an Equations Reordering method.

• Activate Chaining with a previously solved solution. For more information, see Chaining solutions (Simcenter Samcef).

Estimation of damping in viscoelastic material

If you set damping data in some physical properties and if those physical properties refer to a material with viscoelastic properties, you can specify the frequency at which the damping effect must be computed:

You can define this value in the Damping with Viscoelastic Material group in the Analysis page.

For more details, refer to the .ALGO FREQ command in the Simcenter Samcef documentation.

Evaluate time-dependent boundary conditions

When a time-varying boundary condition is included in a solution that varies over a different independent domain than the boundary condition, the software evaluates the boundary condition using the Evaluation Time value that you define in the Boundary Condition Control Variables in the General page of the solution.

User-defined solver parameters

In the User page of the solution, you can manually define solver parameters for the .ALGO, .SAM, or .GEL Samcef commands.

Note:

The text you add must be compliant with the Simcenter Samcef command language terminology. For more information, see the Simcenter Samcef documentation.
