Solution dialog box (Simcenter Samcef Standalone Buckling Analysis)

General page

Foreground Run
Run Job in Foreground	Runs the Samcef job run in the foreground.
User-Defined Text
Prolog****Epilog	Specifies the User Defined Text to prepend (Prolog) or append (Epilog) to the solver input file. For more information, see Customizing a Simcenter Samcef input file with user defined text.
Boundary Condition Control Variables
Evaluation Time	If your boundary conditions use time-dependent fields, you can define the time at which the field will be evaluated.The same time value is used for all the time-dependent fields.This time value is also used for the Mechanical Loads Summary.

Analysis page

Temperature
Default Reference Temperature (.GEL TEMP)	Specifies the reference temperature used to compute thermal strains. For more information, see Reference and Initial Temperatures in Samcef (Simcenter Samcef).
Modes Selection
Number Of Eigenvalues	Sets the number of eigenvalues to compute. Note: Rigid modes are included in this number of computed eigenvalues.For more information, see the LANCNVA parameter of the Samcef .ALGO command.
Lower Frequency	Select the Lower Frequency check box to display the V1 list. The V1 specifies the lower frequency bound.For more information, see the V1 parameter of the Samcef .ALGO command.
Eigenvalues
Upper Frequency	Select the Upper Frequency check box to display the V2 list. The V2 list specifies the upper frequency bound.For more information, see the V2 parameter of the Samcef .ALGO command.Note: If the range is not specified (the default), Samcef computes the first Number Of Eigenvalues lowest frequencies. If the range is specified, Samcef computes up to Number Of Eigenvalues eigenvalues in this given range.
Effective Masses
Effective Masses Option	Enables the effective modal masses computation. For more information, see the Samcef modal solver documentation.
Option	Appears when the Effective Masses Option check box is selected.Specifies the effective masses computation option. Calculation of the Effective Modal MassesComputes and prints the effective modal masses.Calculation of the Effective Modal Masses and Distances to Structural AxesComputes and prints the effective modal masses and their positions in the global structural coordinate system.No Calculation of the Effective Modal MassesPrevents the computation of modal masses.For more information, see the MEFIMP parameter of the Samcef .ALGO command.Note: Effective modal masses values, their positions, the modal participation factors, and the modal reactions are printed only in the Samcef .res output listing file. They are not available in post-processing.For more details about the Effective Masses Option, see the Samcef modal analysis manual.
The following check boxes appear when you select the Effective Masses Option check box, and you select Calculation of the Effective Modal Masses or Calculation of the Effective Modal Masses and Distances to Structural Axes from the Option list.
Calculation of the Modal Participation Factors	Computes and prints the participation factors.For more information, see the PARTIMP parameter of the Samcef .ALGO command.
Calculation of the Modal Reactions	Computes and prints the modal reactions.For more information, see the REAIMP parameter of the Samcef .ALGO command.
Curvature for shells and beams
Compute Curvature for Mindlin Shells and Beams (.ALGO MINO)	Computes the mean normals for Mindlin elements. These mean normals are used to introduce a curvature at the element level. For more information, see the MINO parameter of the Samcef .ALGO command.
Threshold Angle (.ALGO SNORM)	Appears when the Compute Curvature for Mindlin Shells and Beams (.ALGO MINO) check box is selected.Specifies the angle value above which the mean normals are not computed. For more information, see the SNORM parameter of the Samcef .ALGO command.

Solver Parameters page

Solver Type
Solver (.SAM MF)	Specifies the solver type.SparseRecommended for a linear static solution.FrontalReserved for a very few specific cases that are described in the Samcef documentation.For more information, see the MF parameter of the Samcef .SAM command.
Advanced
Equations reordering Method (.ALGO MMFOPT)	Appears when the Sparse solver is selected from the Solver (.SAM MF) list.Specifies the equations reordering method. Select Automatic to allow Samcef to choose the best method during the solve. You can select the METIS or the MMD ordering method. You can also let Samcef choose the best of both methods during the solve by selecting Automatic from the list.For more details on the METIS and MMD ordering methods, see the solution methods chapter of the Samcef documentation.For more information, see the MMFOPT parameter of the Samcef .ALGO command.
Execution Stop Stage (.SAM ISTO)	Lets you specify the stage at which you want to stop the computation of the solution.Data AnalysisStops the computation after the data analysis.Element GenerationStops the computation after the generation of the elements.Stiffness Matrix DiagonalisationStops the computation after the check of the stiffness matrix and its diagonalisation.Stiffness Matrix TriangulationStops the computation after the triangulation of the stiffness matrix and the condensation of loads.**Buckling Loads Computation.**Stops the solve after the buckling loads computation.**Buckling Modes Computation.**Stops the solve after the buckling modes computation.**Buckling Modes Normalization.**Stops the solve after the buckling modes normalization.Note: This is the default. This stage matches a complete solve.For more information, see the ISTO parameter of the Samcef .ALGO command.

Output page

Output Requests
Output Requests	Specifies the output request. For more information, see Samcef output requests.

Chaining page

Activate Chaining	Activates chaining. For more information, see Chaining solutions (Simcenter Samcef) and Chaining with a standalone buckling solution (Simcenter Samcef).

User page

User Parameters
User Parameters for .ALGO	Lets you specify user parameters for the .ALGO Samcef command.
User Parameters for .SAM	Lets you specify user parameters for the .SAM Samcef command.
User Parameters for .GEL	Lets you specify user parameters for the .GEL Samcef command.

Note:

The added texts must be compliant with the Samcef Command Language terminology. For more information, see the Samcef documentation.
