                                      Click the Sketching tab and select Draw.  Choose Line to
                                        create a lower horizontal line with the vertices of (0,0) and
                                        (0.5,0).  This is done by clicking at the coordinates of (0,0)
                                        of the model, drag the cursor to the coordinates of (0.5,0),
                                        and  click  the  mouse  again.  Click  on  Generate  (the  icon
                                        with yellow lightning on the upper-left part of the screen).
                                        The lower horizontal line will pop up in dark green.
                                      Follow the same procedure to create the left vertical line, as
                                        well as the upper horizontal line.
                                      Then, create the right vertical line in the same manner with
                                        the  vertices  of  (2,1)  and  (2,0.5).    This  length  can  be
                                        shortened  to  0.454  by  selecting  the  Dimensions tab
                                        followed  by  General.    The  exact  length  is  obtained  by
                                        clicking at the line and drag the cursor slightly to the right,
                                        then  change  the  value  of  V1 in  the  Details  window  to
                                        0.454, hit Enter and click on Generate.




















                                      The last inclined line can now be drawn by selecting Draw
                                        and choose Line.  Then, click at the lower left and upper
                                        right vertices, respectively, followed by Generate.
                                      The next important step is to go to the Concept tab on top
                                        of the screen and select Surfaces From Sketches.
                                      Select  the  Sketch1,  the  domain  boundary  will  become
                                        yellow.
