 #!Rall132 Example 1. Scalar and Vector Data on a Regular Grid. 
#!N #!EC #!N #!N This example illustrates the importation of a 
data file that contains two variables (pressure and velocity) in spreadsheet 
style. The data are in row majority order (last index varies 
fastest) and organized in four columns: the first contains the pressure 
data; the other three, the velocity components. The grid is 5 
* 8 * 6. #!N #!I0 #!N  #!F-adobe-times-medium-r-normal--18*   #!N #!N #!I30 
#!N 1. In the Data Prompter initial dialog box, select  #!F-adobe-times-bold-r-normal--18*   
Grid or Scattered File #!EF , then select the leftmost button 
in the row labeled  #!F-adobe-times-bold-r-normal--18*   Grid type #!EF (regular grid). #!N 
#!I30 #!N 2. Set  #!F-adobe-times-bold-r-normal--18*   Number of variables #!EF to "2." 
#!N #!I30 #!N 3. For  #!F-adobe-times-bold-r-normal--18*   Data organization #!EF , activate 
the  #!F-adobe-times-bold-r-normal--18*   Columnar #!EF toggle button. #!N #!I30 #!N 4. Click 
on  #!F-adobe-times-bold-r-normal--18*   Describe Data #!EF to bring up the simplified prompter. 
#!N #!I30 #!N 5. Enter the path name of the data 
file in the  #!F-adobe-times-bold-r-normal--18*   Data file #!EF field: #!CForestGreen #!N #!N 
 #!F-adobe-courier-bold-r-normal--18*   #!N /opt/local/dx/samples/data/spreadsheet_2var #!EF #!N #!N #!EC #!N #!I30 #!N 6. 
Enter the values "5," "8," and "6," in that order, in 
the first three  #!F-adobe-times-bold-r-normal--18*   Grid size #!EF fields. #!N #!I30 #!N 
7. In the  #!F-adobe-times-bold-r-normal--18*   Field list #!EF , change the name 
"field0" to "pressure" and confirm the change by clicking on the 
 #!F-adobe-times-bold-r-normal--18*   Modify #!EF button at the bottom of the panel. #!N 
#!I30 #!N 8. Change the name of "field1" to "velocity" and 
its  #!F-adobe-times-bold-r-normal--18*   Structure #!EF to "3-vector." (See Steps 9 through 11 
of Example 6 in the preceding section,  #!Lmltvrx6,dxall129 h Example 6. Deformed (Warped) Regular Grid  #!EL  , for procedure.)
