EEMS 11 allows you to export the current view of the velocity vector in the 2DH View to a variety of formats such as the Tecplot file, Data file, and shapefile.

To do this, the user should go to the 2DH View and add a velocity vector layer as shown in Exporting a Velocity Vector Layer#Figure 1. By default, when you display the velocity vector, the velocity vector will be displayed on each grid cell, by Right Mouse Click (RMC) on the layer and select Properties, then the Vector2D Layer Properties form will appear as shown in Exporting a Velocity Vector Layer#Figure 2.

From this form, select one of three options from the Vector Location frame.

  • Cell Centroids: When this option is selected, the user can enter a number in the Skip I, Skip J, and Skip K. EE sets 0 as the default value for these boxes. This means that the velocity vector will be displayed in every grid cell and all layers. Entering a number greater than 0 will decrease the number of velocity vectors displayed.

  • Regular Points: When this option is selected, a form showing Delta X and Delta Y text boxes will be displayed as shown in Exporting a Velocity Vector Layer#Figure 3 . The number entered is the interval distance in meters between vectors. EE sets 0 as the default value for these boxes.

  • Location File: When this option is selected, the Select button will appear to browse to the location file as shown in Exporting a Velocity Vector Layer#Figure 4. This file uses pre-defined format and created by the user. The file has two columns (X and Y), which are locations where the vectors will be located and displayed.

After one of the three above options is selected, click the OK button to apply the selection and close the form. Return the Layer Control, RMC on the velocity vector layer then select Export to option as shown in Exporting a Velocity Vector Layer#Figure 5. The Save Data File form will appear as shown in Exporting a Velocity Vector Layer#Figure 6. Select the data file format to save out (there are three data types that can be selected from the drop-down arrow: *.plt, *.dat, *.shp). Then enter a name for the file and click the Save button.
