Structural nonlinear solution options (Simcenter Samcef)

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

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

• Define a Restart Time (.ALGO TBEG) and set options for the computed time step.

• Define initial conditions: you can force an Initial Static Computation (.ALGO IREF), you can check the stiffness matrix and kinematic modes, or you can ensure Equilibrium with the inertia forces (.ALGO IREF) prior to the solve.

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

• Specify Output Requests.

• Specify the Solver Type algorithm to use or define several Contact Friction parameters.

• Define Geometric Nonlinearities, Coupling Options, Equations Reordering methods.

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

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.
