Case6 Displacement-based bed length preservation
Contents
The data file for this exercise is located in Rest_001/Exercices/Case6/Data. Look for ! TODO text in the datafile and follow the instructions.
The aim of this exercise is to learn to define the data to preserve bed length of the top surface during restoration. This method is displacement-based and requires to define a pin location from which facet distances are calculated. Note that displacement on the top surface nodes during flattening is fully prescribed (in horizontal and vertical directions) to honour bed length preservation.

To perform this exercise:
1Modify the Restoration_data as shown below.

* Restoration_data ! --------------------------------- Restoration_surface "Restoration_surface" Operation_type "Translate" Move_to_surface_type "Bed_length" Pin_coordinates IDM=1 /X coord./ 7000.0
|
1The Move_to_surface_type keyword is defined and set to "Bed_length" (bed length will be preserved). 2The Pin_coordinates must be provided. Here pin location is set to X=7000 m (center) to coincide with the Pin plane. 3Note that Restoration_data is re-defined in the next stage. |
Results
The result files for the project are in directory: Rest_001\Exercises\Case6\Results. Note that the initial and final bed-lengths are identical.
