Elmer/GiD tutorial in 2D                                     ML 16.5.2004

1) Make sure that the folder elmer.gid is copied in \GiD\ProblemTypes.
   Then, "elmer" should be a valid problem type for GiD and visible in
   Data -> Problem type.

2) Invoke GiD and choose File -> New 

3) Create a square: Geometry -> Create -> Object -> Rectangle. Give:

       First corner point: 0 0
       Second corner point: 1 1

4) Right-click the mouse and choose a) Render -> Flat lighting b) Rotate ->
   Trackball. Select a nice view point and give the command "zoom frame".

5) Choose Data -> Problem type -> elmer

6) Assing boundary conditions to the boundary lines by choosing Data -> 
   Condition. Select "LineCondition" with Index=1 and assign it to all four
   boundary lines of the rectangle. NOTE: Only the boundary elements with
   Index>0 will be written in the mesh file "mesh.boundary".

7) Choose Data -> Materials and assign Index=1 to the surface of the
   rectangle. NOTE: Only the bulk elements with material Index>0 will be
   written in the mesh file "mesh.elements".

8) Set Utilities -> Preferences -> Meshing -> Mesh always by default: lines
   This option is needed to generate the mesh.boundary file.

9) Select Meshing -> Generate. Give size=0.14. As a result, we should
   get 28 linear boundary elements, 104 triangular bulk elements, and 67
   nodes.

10) Save the project: File -> Save as. 

11) Save the mesh in elmer-format by choosing Calculate -> Calculate. The
    mesh.* files written by GiD can be found from the project-folder.
