                        1.  Establish the Command Log File
                           First, solve the problem interactively and then save the database log file.
                           •  Start ANSYS
                                    File -> Save As -> Tutorial 1 -> OK
                           •  Use the structural solid element PLANE82 for FEM modeling:
                                 Preprocessor -> Element Type -> Add/Edit/Delete ->
                                  Add -> Structural Mass-Solid -> Select 8node 82 ->
                                        OK -> Options -> Element Behavior:
                                      Select Plane Stress w/thk -> OK -> Close
                           •  Enter Real Constants for the element type chosen:
                              Preprocessor -> Real Constants -> Add/Edit/Delete -> Add
                                 -> OK -> Enter Thickness THK = 0.3 -> OK -> Close
                           •  Enter material property data for specified steel:
                                 Preprocessor -> Material Props -> Material Model ->
                                 Structural -> Linear -> Elastic -> Isotropic  ->  Enter
                                 Young’s  modulus  EX  =  200e9  and  Poisson’s  ratio
                                           PRXY = 0.32 -> OK -> Close
                           •  Create geometry for two similar rectangles 1.5 cm by 3 cm at
                              locations (2.25,0.5) and (7.25, 0.5):
                               Preprocessor  ->  Modeling  ->  Create -> Areas-Rectangle
                               ->  By  2  Corners ->  In dialogue box enter WP X = 2.25,
                                  WP Y = 0.5, Width = 3, Height = 1.5 -> Apply ->
                                    Enter values for next rectangle: WP X = 7.25,
                                     WP Y = 0.5, Width = 3, Height = 1.5 -> OK
                           •  Create geometry for three circles, all of 1.25 cm radius:
                               Preprocessor -> Modeling -> Create -> Areas -> Circle ->
                               Solid Circle -> In dialogue box enter WP X = 1.25, WP Y =
                               1.25, Radius = 1.25 -> Apply -> Enter values for next circle
                                -> WP X = 6.25, WP Y = 1.25, Radius = 1.25 -> Apply ->
