SOL 401 Multi-Step Nonlinear workflow

Step	Summary	Detailed help topic
1.	Build the finite element (FE) model and Simulation file.	In Pre/Post, define the geometry, material properties, mesh, loads, and constraints as you would for other structural solutions.	Create new FEM and Simulation filesMaterial typesMeshingBoundary conditions
2.	Create contact and glue simulation objects.	In Pre/Post, create surface-to-surface and edge-to-edge contact and glue simulation objects.	Contact and glue conditionsSurface-to-Surface Contact (Simcenter Nastran, Simcenter 3D Multiphysics, Abaqus, ANSYS)Defining parameters for contact conditions (Simcenter Nastran)BCTPARM (contact)Defining parameters for glue conditionsBGPARM (glue)
3.	Create the Simcenter Nastran solution.	In the Solution dialog box, set the Analysis Type to Structural and the Solution Type to SOL 401 Multi-Step Nonlinear.	Create or modify a solution
4.	Configure the solution parameters.	Determine if you want to solve for large displacements and material nonlinearities. On the Bulk Data page:To turn on the geometric nonlinearity needed to solve for large displacements, select the Large Displacements check box.To include plasticity effects, creep effects, damage material properties, and progressive ply failure in the solution, select the Material Nonlinearity check box.	Solution dialog box (Nastran), Bulk Data page
5.	Set the nonlinear control parameters.	The Nonlinear Control Parameters modeling object includes settings for the convergence and iteration control parameters, bolt preload parameters, general solution parameters, stiffness control parameters, contact parameters, plasticity and creep control parameters, and time step control parameters.	Solver-specific modeling objectsNonlinear Control Parameters dialog box (Simcenter Nastran SOL 401/Simcenter 3D Multiphysics)
6.	Request output for the contact, glue, creep, strain, structural, and so on.	Create Structural Output Requests modeling objects.	Supported outputRequesting output for Nastran analysesStructural, FRF, and Thermal Output Requests dialog boxes (Nastran)
7.	Create subcases.	Select the analysis types, determine how you want to sequence the subcases, and define the time steps.	Create or modify a solution step or subcaseSolution Step/Subcase dialog box (Nastran)Cyclic symmetric subcaseFourier harmonic solutionNonlinear buckling (SOL 401)Defining solution time steps
8.	Solve the model	The Solution Monitor contains information about the status of your solution, and the Simcenter Nastran .f06 output file contains the requested results from your analysis. To locate the Simcenter Nastran .f06 file, right-click the solution and select Browse.	Solve the modelSolution Monitor
9.	Review the .f06 results file.	The .f06 file results file contains time step entries for checking convergence; contact conditions; error, warning, and information messages; and all requested results.	Simcenter Nastran Output Files
10.	Post process the results.	Use the Post-Processing Navigator and the Results tab to manage and view results. Note: If the model contains contacts, set the deformed scale to 1.0. Otherwise, the results may show penetration between objects.	Post-processingControl the display of deformation
