Etc.5.6.2. Using the Load Step File Method
The load step file is a convenient method to use when you want to solve problems while you are away
from your terminal or PC (for example, overnight). It involves writing each load step to a load step file
(via the LSWRITE command or its GUI equivalent) and, with one command, reading in each file and
obtaining the solution. See Loading (p. 21) for details about creating load step files.
To solve multiple load steps, issue the LSSOLVE command (Main Menu> Solution> From LS Files).
LSSOLVE is actually a macro that reads in the load step files sequentially and initiates the solution for
each load step. An example command input for the load step file method is shown below:
/SOLU! Enter SOLUTION! Load Step 1:
D,...! Loads
SF,...
NSUBST,...! Load step options
KBC,...
OUTRES,...
OUTPR,...
LSWRITE! Writes load step file: Jobname.S01
! Load Step 2:
D,...! Loads
SF,...
NSUBST,...! Load step options
KBC,...
OUTRES,...
OUTPR,...
LSWRITE! Writes load step file: Jobname.S02
0
LSSOLVE,1,2! Initiates solution for load step files 1 and 2See the Command Reference for a discussion of the NSUBST,KBC,OUTRES,OUTPR,LSWRITE, and LS-
SOLVE commands.
5.6.3. Using the Array Parameter Method
This method, mainly intended for transient or nonlinear static (steady-state) analyses, requires knowledge
of arra y parameters and do-loops, which are part of APDL (ANSYS Parametric Design Language). See
the ANSYS Parametric Design Language Guide for information about APDL.The arra y parameter method
involves building tables of load versus time using arra y parameters and is best explained by the following
example.
