Solution dialog box (Simcenter Samcef Linear Static Analysis)

In a Linear Static Analysis solution, you can define several options for the Simcenter Samcef linear static solver.

General page

Foreground Run
Run Job in Foreground	Runs the Simcenter 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).
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 solution.FrontalReserved for a very few specific cases that are described in the Simcenter Samcef documentation.MUMPS ParallelSuitable in parallel mode.****For more information, see the MF parameter of the Samcef .SAM command.
Contact Method Penalty
Contact Friction Convergence	Lets you specify the convergence criterion of Newton's iterative method. For more information, see the PRECNEWT parameter of the Samcef .ALGO command.
Contact Friction Convergence Value	Appears when the Contact Friction Convergence check box is selected.Specifies the convergence criterion of Newton's iterative method.
Contact Friction Penalty Precision	Lets you specify the independence of the solution. For more information, see the PRECPENA parameter of the Samcef .ALGO command.
Contact Friction Penalty Precision Value	Appears when the Contact Friction Penalty Precision check box is selected.Specifies the independence of the solution.
Advanced
Equations reordering Method (.ALGO MMFOPT)	Appears when Solver (.SAM MF) is set to Sparse.Specifies the equations reordering method. Select Automatic to allow Simcenter Samcef to choose the best method during the solve. You can select the METIS or the MMD ordering method. You can also let Simcenter Samcef choose the best of both methods during the solve by selecting Automatic from the list.For more information on the METIS and MMD ordering methods, see the solution methods chapter of the Simcenter 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.Displacement ComputationStops the solve after the displacements computation.Stress ComputationStops the solve after the stress computation.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 output requests. For more information, see Samcef output requests.
Superelement Results
Generate Nodal/Elemental Results in Superelements	Computes results in superelements.
Reactions
Internal forces induced by linear constraints (.ALGO REAC)	Specifies how to include the internal forces in reactions induced by linear constraints.IncludeIncludes the internal forces in reactions induced by linear constraints.ExcludeExcludes the internal forces in reactions induced by linear constraints.Solver DefaultLets the solver make the best choice.For more information, see the REAC parameter of the Samcef .ALGO command.

Chaining page

Activate Chaining	Activates chaining. For more information, see Chaining solutions (Simcenter Samcef) and Chaining with a linear static 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 Simcenter Samcef documentation.
