GiD Procedure

1. start GiD
2. set problem type:
   "Data/Problem type/inp"
3. create object(s)
4. assign "Conditions" (=property ids=grain numbers) - the corresponding material parameters are later defined in project.krn: material properties in the appropriate line (line number=property id):
   "Data/Conditions"
5. set grain number
   "grain number 1"
6. "Assign"
7. select all objects, which should have property id ”1”
8. press the "Finish" button or the Esc key when finished
9. Repeat 5-8 if necessary
10. Just in case:
    "Geometry/Delete/Point"
    "Geometry/Delete/Line"
    "Geometry/Delete/Surface"
    only volumes should be left over!
11. generate a tetrahedral finite element mesh:
    "Meshing/Generate"
12. Enter the size of elements, 
13. save the project:
    "Files/Save" "sphere"
14. generate the inp file:
    Calculate/Calculate
15. rename the inp file:
    mv sphere.dat sphere.inp
