2.2.2.1. Access the Solution Controls Dialog Box
To access the Solution Controls dialog box, choose menu path Main Menu> Solution> Analysis Type>
Sol'n Controls. The following sections provide brief descriptions of the options that appear on each
tab of the dialog box.For details about how to set these options, select the tab that you are interested in
(from within the ANSYS program), and then click theHelpbutton.Nonlinear Structural Analysis (p. 193)
also contains details about the nonlinear options introduced in this chapter.
2.2.2.2. Using the Basic Tab
The Basic tab is active when you access the dialog box.
The controls that appear on the Basic tab provide the minimum amount of data that ANSYS needs for
the analysis. Once you are satisfied with the settings on the Basic tab, you do not need to progress
through the remaining tabs unless you want to adjust the default settings for the more advanced
controls. As soon as you click OK on any tab of the dialog box, the settings are applied to the ANSYS
database and the dialog box closes.
You can use the Basic tab to set the options listed in Table 2.1: Basic Tab Options (p. 11). For specific
information about using the Solution Controls dialog box to set these options, access the dialog box,
select the Basic tab, and click the Help button.

Specify analysis type [ANTYPE,
NLGEOM]- Specifying the Analysis Type and Analysis Options in the
Basic Analysis Guide - Nonlinear Structural Analysis (p. 193) in the Structural
Analysis Guide - Restarting an Analysis in the Basic Analysis Guide
Control time settings, including:
time at end of load step [TIME],- The Role of Time in Tracking in the Basic Analysis Guide
automatic time stepping [AUTOTS], • Setting General Options in the Basic Analysis Guide
and number of substeps to be taken
in a load step [NSUBST or DELTIM]
Specify solution data to write to
database [OUTRES]- Setting Output Controls in the Basic Analysis Guide
Special considerations for setting these options in a static analysis include:
- When setting ANTYPE and NLGEOM, choose Small Displacement Static if you are performing a new
analysis and you want to ignore large deformation effects such as large deflection, large rotation, and
large strain. Choose Large Displacement Static if you expect large deflections (as in the case of a long,
slender bar under bending) or large strains (as in a metal-forming problem). Choose Restart Current
Analysis if you want to restart a failed nonlinear analysis, if you have previously completed a static ana-
lysis and you want to specify additional loads, or if you wish to use the Jobname.RSX information from
a previous VT Accelerator run. Note that in a VT Accelerator run, you cannot restart a job in the middle;
you can only rerun the job from the beginning with changes in the input parameters.
