Translations:Add FEM Constraint Tutorial/5/en


 * 1) Create document object: The document object that resides inside the analysis and though which the constraint can be parametrized and attached to boundaries.
 * 2) Create GUI command: Add a command to the FEM workbench that adds a flow constraint to the active analysis.
 * 3) Create a task panel: The task panel is necessary to allow the user to set the boundaries at which he wants to set the velocity constraint. It also makes entering the parameters a little more user friendly.
 * 4) Extend elmers writer: Add support for the new constraint to Elmer by extending its sif file exporter.
