Loading SUTRA (Version 2.2, 2.1, and 2.0) Data

Before loading data, please check that the "nod", "ele" (if used), and "inp" files are all in the same folder.

  1. Click the File menu and select New.
  2. If changes to the previous MV document have not been saved, a dialog box is displayed that allows you to click: Yes to save changes or No to discard changes.
  3. The Model Selection dialog box is displayed. Select SUTRA  from the drop-list box, and then click OK.
  4. The SUTRA Data File dialog box is displayed. Specify the "nod" file in the first text box by clicking the corresponding Browse button and navigating to the file. (See note 1 below.)
  5. If velocity data have been saved in an "ele" file, it can optionally be specify in the second text box by using the corresponding Browse button. Otherwise, leave the text box blank.
  6. Specify the SUTRA input data file ("inp" file) third text box by using the corresponding Browse button.
  7. Click OK.
  8. A dialog box gives you the option to convert the text files to binary files. If you click No, Model Viewer will read from the nod, ele, and imp files specified above. If you click Yes, will convert the data in these files into binary and save them to a binary file. You will be prompted to supply the name of this file, which should end with .bin. After conversion, the program will read data from the binary file. The original text files are not modified. Conversion to binary format is recommended because Model Viewer can read from a binary file much faster than from a text file.
  9. The Data Selection dialog box is displayed. From the drop-list boxes, select the time step and data type for the initial display. (Note that the number in parentheses indicates the time step.) Then click OK.

After the model data are loaded, the opening display will be a grid outline viewed from overhead (from +z axis toward -z direction) at the selected time in Step 9 above.

Scalar values (for example, pressure, concentration, etc.) at the selected time are used to set the color bar as follows:

If velocity data (in the ele file) were loaded in Step 5, then velocity vectors are scaled so that, for the selected time, the length of the vector with the highest magnitude is approximately one-tenth the diagonal distance across the bounding box.

Note:

  1. If you want to load a previously created binary file, you may specify it in the first text box using the Browse button. Then, click OK. In this case, it is not necessary to specify the nod, ele, or inp files.
