You can restrict data being listed to a range of time or frequency. This and other listing controls are
available through the "Lists" tab under Data Properties dialog. In addition to setting the range of time
or frequency, this dialog also allows you to:



  • Control the number of lines before repeating headers on the listings.

  • Additionally print the extreme values of the selected. variables.

  • Specify printing every 'n'th data point.

You can use the PRVAR command (Main Menu> TimeHist Postpro> List Variables) to list up to six
variables in tabular form. This is useful if you want to find the value of a result item at a specific time
or frequency. You can control the times (or frequencies) for which variables are to be printed. To do
so, use one of the following:


Command(s):NPRINT,PRTIME
GUI: Main Menu> TimeHist Postpro> Settings> List


You can adjust the format of your listing somewhat with the LINES command (Main Menu> TimeHist
Postpro> Settings> List). A sample PRVAR output is shown below.


Sample Output from PRVAR

***** ANSYS time-history VARIABLE LISTING *****
TIME 51 UX 30 UY
UX UY
.10000E-09 .000000E+00 .000000E+00
.32000 .106832 .371753E-01
.42667 .146785 .620728E-01
.74667 .263833 .144850
.87333 .310339 .178505
1.0000 .356938 .212601
1.3493 .352122 .473230E-01
1.6847 .349681 -.608717E-01

When a complex variable consists of real and imaginary parts, the PRVAR command lists both the real
and imaginary parts by default.You can work with real and imaginary, or amplitude and phase angle
using the PRCPLX command.


Another useful listing command is EXTREM (Main Menu> TimeHist Postpro> List Extremes), which
prints the maximum and minimum Y-variable values within the active X and Y ranges. You can also
assign these extreme values to parameters using the *GET command (Utility Menu> Parameters> Get
Scalar Data). A sample EXTREM output is shown below.


Sample Output from EXTREM
