Step02 Use and Reflate SE
Contents
The data files for the project is in: SuEl_001\Case01\Step02\Data.
In the present step we are going to run the simulation using the super element created during Step01. Model definition data is identical to the previous case (data for the problem to be solved is fully defined). The only change is found in the Super_element_control data structure as shown below.

1.In order to use the previously created super element Solution_type must be set as "Use". 2.The file containing the description of the super element matrix created in the previous step must be specified (without file extension). |
Results
The results for the project are located in SuEl_001\Case01\Step02\Results.
Below is shown a comparison of the results obtained using the super element workflow with the reference solution for a standard simulation. As can be seen the downward push exerted by the Platten to the plastic Billet has led to compression downward compression, expansion towards the east direction (which was left free) and the development of a plastic strain localization. In addition, the results of the super element simulation for the Billet are identical to the reference solution. It should be noted that the super element solution does not provide results for the Platten at it has been condensed into a super element and hence all that the code has calculated so far are the boundary displacements of the Platten due to the imposed downward displacement at the top surface.
Comparison of results obtained using the super element approach with the reference solution (standard simulation)
The details of the CPU time obtained for the present case from a sequential run on an Intel processor with 3.60 GHz clockspeed is shown in the following table:
