Other Step Parameters for Visco, Coupled Thermal-Structural Steady-state, Transient, and Complex Eigenvalue Extraction

Properties
Solution Technique	Controls the technique that Abaqus uses to solve the nonlinear equations.Newton MethodSpecifies that Abaqus use the standard Newton method for solving nonlinear equations.Quasi-Newton MethodAvailable for Visco stepsSpecifies that Abaqus use the quasi-Newton method for solving nonlinear equations.Separated Solution SchemeAvailable for Coupled Thermal-Structural Steady-state and Transient steps.Specifies that Abaqus solve the mechanical and thermal solutions separately for each field.This option corresponds to the Abaqus *SOLUTION TECHNIQUE keyword.
Iterations Before Kernel Matrix is Reformed	Appears when Solution Technique is set to Quasi-Newton Method.Lets you specify the number of quasi-Newton iterations Abaqus can perform before reforming the kernel matrix.

Other Step Parameters for Transient Modal Dynamic, Response Spectrum, Complex Eigenvalue Extraction, Steady-State Modal Dynamic Steps

Eigen Modes Selection
Use Modes Extracted in Prior EigenFrequency Step/Use All Modes Extracted in Prior EigenFrequency Step	Select this option to use all modes extracted in the prior Transient Modal Dynamic step, including residual modes if they were activated in the modal superposition.
Mode Selection	Appears when the Use Modes Extracted in Prior EigenFrequency Step/Use All Modes Extracted in Prior EigenFrequency Step check box is cleared.Specifies a Select EigenModes modeling object. Select an existing modeling object from the list or click Create Modeling Object to create a new one.Click Edit to edit the selected modeling object.For more information, see Select EigenModes dialog box (Abaqus).This option corresponds to the *SELECT EIGENMODES keyword.

Select an existing modeling object from the list or click Create Modeling Object to create a new one.Click Edit to edit the selected modeling object.For more information, see Global Damping dialog box (Abaqus).
Define Damping Controls	Appears for Transient Modal Dynamic and Steady-State Modal Dynamic.Lets you control the type (viscous, structural) and source of damping (material, global) within the step definition.This option corresponds to the *DAMPING CONTROLS keyword.Note: You can only select Damping Controls when you also run a natural frequency extraction (Frequency Perturbation) analysis with the SIM architecture. Select the Activate SIM Software Architecture option on the General page of the Solution Step dialog box in a Frequency Perturbation step.For more information see, TSIM architecture in the Abaqus environment.
Damping Control	Appears for Transient Modal Dynamic and Steady-State Modal Dynamic.Appears when the Define Damping Controls check box is selected. Specifies a Damping Control modeling object. Select an existing modeling object from the list or click Create Modeling Object to create a new one.Click Edit to edit the selected modeling object.For more information, see Damping Controls dialog box (Abaqus).
Based Motion
Specify Base Motion	Appears for Transient Modal Dynamic and Steady-State Modal Dynamic.Lets you specify the degree of freedom and one of the following depending on the type of analysis:For a Transient Modal Dynamic analysis, the time history of the motion.For a Steady-State Modal Dynamic analysis, the frequency history of the motion.This option corresponds to the *BASE MOTION keyword.
Base Motion Definition	Appears for Transient Modal Dynamic and Steady-State Modal Dynamic.Appears when the Specify Base Motion check box is selected. Specifies a Base Motion modeling object. Select an existing modeling object from the list or click Create Modeling Object to create a new one.Click Edit to edit the selected modeling object.For more information, see one of the following depending on the type of analysis:For a Transient Modal Dynamic analysis, see Base Motion dialog box (Abaqus).For a Steady-State Modal Dynamic analysis, see Base Motion - Frequency dialog box (Abaqus).

Other Step Parameters for Explicit Dynamic and Dynamic Coupled Thermal-Stress Steps

Bulk Viscosity Parameters
Bulk Viscosity	Sets how bulk viscosity is determined. You can change the bulk viscosity from step to step. Abaqus uses the values in subsequent steps until the values are redefined. Use Bulk Viscosities From Previous StepSpecifies that Abaqus use the bulk viscosities from the previous step.Apply Specific Bulk ViscositySpecifies that Abaqus use new values for bulk viscosity specified in Linear Bulk Viscosity and Quadratic Bulk Viscosity.This option corresponds to the Abaqus *BULK VISCOSITY keyword.
Linear Bulk Viscosity	Appears when Bulk Viscosity is set to Apply Specific Bulk Viscosity.Lets you specify the linear bulk viscosity (b1).
Quadratic Viscosity	Appears when Bulk Viscosity is set to Apply Specific Bulk Viscosity.Lets you specify the quadratic viscosity (b2).
General Contact Control
Contact Property Assignments	Available for the Explicit Dynamic step.Specifies a contact property assignment modeling object. Select a modeling object from the list or click Create Modeling Object to create one. A Contact Property Assignment modeling object lets you assign non-default properties.For more information, see Defining contact properties for general contacts (Abaqus).
