Case 4 Displacement Reinitialization

 

In this exercise a displacement reinitialization is added after the previous stages of geostatic initialization in a similar manner as explained in Geost_001 Case 3 example.

 

To perform this exercise copy the datafile from Case3 as a template. Then copy and paste Geostatic_control_data and Control_data data structures to add an extra control stage. Then modify the geostatic control data structure in order to perform displacement reinitialization.

 

Stage 5: Displacement Reinitialization

Data File

 

 

* Geostatic_control_data

! ----------------------------------------

 Displacement_reinit_flag  1  

 

   

* Control_data

! ========================================

 Control_title             "Disp reinit"

 Solution_algorithm                    1  

 Maximum_number_time_steps       1000000

 Duration                           0.25

 Factor_critical_time_step           0.5

 Output_frequency_plotfile            -1

 Screen_message_frequency            500

 Output_frequency_restart             -1  

 

1Displacement reinitialization is performed in this stage by setting Displacement_reinit_flag to 1 in Geostatic_control_data.

 

2Control_data is identical to the first stage (see Case1).
