Last week a customer complained about the necessary steps to remove a component from any vector variable. In his case he wanted to project streamlines on the midplane in Y direction around a car surface. The standard way in EnSight is to get the X and Z components of the velocity vector and add those to the MaceVect Calculator function with zero as Y components. This new variable should be renamed and can be used for the desired streamlines. Too unhandy for the user.
This routine does all steps automatically. It launches a small GUI which offers a combo list with all vector variables in the loaded data. The user has to select the component that has to be removed and click OK. The routine will create a new variable on all parts which als called original_variable_name_component-0 (e.g. velocity_Y-0).
This routine is written as a user defined tool. If you have an existing directory for your own tools just put it together with the image into that directory. Otherwise it can be used as a standalone tool as well if line 66 is activated. Please contact me if you have any problems (email@example.com).
