External Superelement
External Superelement Type	Lets you specify the type of superelement to import:ANSYSImport an ANSYS superelement from a .odb file.Nastran OP2/OP4Import a Nastran superelement (stiffness matrix, mass matrix, and load vector) defined in the .op2 and .op4 ASCII files.Nastran DMIGImport a Nastran superelement defined under a DMIG format.PERMASImport a PERMAS superelement.Type a path and file name or click Browse to browse to the location.For more information, see the .INT command in the Simcenter Samcef documentation.
Use Sequential Cards Reading	Appears when you select Nastran DMIG from the External Superelement Type list.By default, with the Use Sequential Cards Reading cleared check box, Simcenter Samcef will import the DMIG as a DMIG TYPE 3.If you select this check box, Simcenter Samcef will import a standard sequential DMIG.For more information on the DMIG conversion, see the .INT command in the Simcenter Samcef solver documentation.

Analysis

Appears when Superelement Type is set to Dynamic or Static.

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
Appears when Superelement Type is set to Dynamic.
Number Of Eigenvalues	Sets the number of eigenvalues to compute. 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.
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), Simcenter Samcef computes the first Number Of Eigenvalues lowest frequency. If the range is specified, Simcenter Samcef computes up to Number Of Eigenvalues eigenvalues in this given range.
Known Modes Selection	Select the Known Modes Selection check box to fetch from a Simcenter Samcef results file a list of mode numbers to be calculated during the superelement modal analysis.
The following options appear when you select the Known Modes Selection check box.
Result File	Type a path and file name or click Browse to browse to the location.
List of Known Modes
You can use the List of Known Modes table to filter the modes to be computed.Use Add All to fetch all the modes from the Result File. Use Remove All to remove all.Select several entries in the table and use Remove to remove these entries.Note: The selected list of mode numbers (not the frequencies) will be used to filter the list of computed modes in the superelement modal analysis so that only the mode numbers calculated in the modal analysis that fit the same numbers as those of the List of Known Modes table will be kept.For more information, see the .SMO command in the Simcenter Samcef documentation.
Compute Residual Vectors	Select the Compute Residual Vectors check box to compute residual vectors that will enrich the normal modes computation.For more details, see the Simcenter Samcef superelement documentation.
Methods
Condensation Algorithm	Select the Condensation Algorithm check box to enable the condensation algorithm.For more details, see the Simcenter Samcef superelement documentation.
Condensation Algorithm Choice	Appears when you select the Condensation Algorithm .Lets you choose the condensation algorithm.Craig and BamptonCraig and Bampton component mode algorithm.Note: You can only choose the Craig and Bampton algorithm if you have not defined Free Boundary Degrees of Freedom constraints in your model.HintzHintz component mode algorithm.Note: You must choose the Hintz algorithm if you have defined Free Boundary Degrees of Freedom constraints in your model.GuyanStandard Guyan algorithm.For more details on these options, see the Simcenter Samcef superelement documentation.
Component Mode Option	Appears when Condensation Algorithm Choice is set to Craig and Bampton or Hintz.Lets you select the component mode option.None****BaseComponent modes base saving.ConstraintConstraint modes restitution.Base ConstraintEnable both options above.For more details on these options, see the Simcenter Samcef superelement documentation.
Superelement Validation
Superelement validation	Select this option if you want to perform a superelement validation.For more details on the dynamic superelement validation, see the Simcenter Samcef modal analysis documentation.
The following options appear when you select the Superelement validation .
Number Of Eigenvalues for Validation	Lets you define the number of eigenvalues to compute during the validation.Note: Usually, the range of frequencies to be considered is smaller than the one used during the modal solution solve.
Validation Lower Frequency	Select this check box if you want to define the lower validation frequency.
Validation V1	Appears when you select the Validation Lower Frequency .Lets you define the lower frequency for the validation.
Validation Upper Frequency	Select this check box if you want to define the upper validation frequency.
Validation V2	Appears when you select the Validation Upper Frequency .Lets you define the upper frequency for the validation.
Damping with Viscoplastic Material
Frequency at which the Damping is Estimated	When Viscoplastic materials are defined in the model, you can specify the frequency at which the damping effects must be computed.
Frequency (.ALGO FREQ)	Appears when you select the Frequency at which the Damping is Estimated check box.Lets you specify the frequency at which the damping effects must be computed.

Solver Parameters page

Appears when Superelement Type is set to Dynamic or Static.

Solver Type
Solver (.SAM MF)	Specifies the solver type.SparseSparse solver—This is the recommended method.FrontalFrontal solver—This method is reserved for a very few specific cases that are described in the Simcenter Samcef documentation.For more information, see the MF parameter of the Samcef .SAM command.

Output page

Appears when Superelement Type is set to Dynamic or Static.

Keep Files
Keep Files for Recovery	By default, all computation files must be kept if you want to perform a superelement recovery.Clear the Keep Files for Recovery check box if you do not plan to perform the superelement recovery; this will reduce the number and the size of the files output during the solve.
Reduced Superelement File
Create Reduced Superelement File	Select this check box if you want to create a reduced superelement database (_reduced.sdb) alongside the classical creation database.This reduced database contains only the basic information of the superelement creation model and does not expose the entire original model. You can share it with other people that want to use your superelement in their model.This reduced database cannot be used for recovery purposes.
Superelement Representations
Create Symbolic Representation (for Post-Processing)	This option creates a symbolic representation (spider) of the superelement that will be used in post-processing.The spider will join the center of gravity of the superelement and the retained nodes.Clear this option if you do not want to use the symbolic representation that Simcenter Samcef can compute.
Create Simplified Representation (for Pre and Post-Processing)	Lets you define a simplified representation that will be used in pre- and post-processing.NoneNo simplified representation is created.AllAll the 2D and 3D elements are used to create the simplified representation. For 3D elements, the skin of these elements is computed with the Samcef .PEAU command.SelectionYou can select the 2D and 3D elements that you want to use to create the simplified representation. For 3D elements, the skin of these elements is computed with the Samcef .PEAU command.Note: This Simplified Representation is the graphical representation that can be used when you add the superelement in an assembly FEM (see Simcenter Samcef superelement graphical representation in an assembly FEM) or when post-processing the results (see Managing superelement representations (Simcenter Samcef)).
Output Requests
Output Requests	Lets you specify classical output requests.
Internal Node Time History Output Preselection	Lets you specify nodal time history curve output requests.
Internal Element Time History Output Preselection	Lets you specify element time history curve output requests.
