1.Solution_type for the second stage is set as "Reflate".

2.Control_data must be set to perform a single step.

3.In the present case we perform the Reflate operation after running the super element simulation again (in the first simulation stage). Nonetheless it should be noted that the "Reflate" operation may be performed from a restart output from the super element simulation.

The results for the project are located in SuEl_001\Case01\Step02b\Results.

Below is shown the comparison between the present case using the super element approach including a subsequent reflate with the reference solution. As can be seen results for both cases are identical. It should be noted that the reflate operation will provide results for the platten in the final configuration while the evolution will be unknown.

Comparison of results obtained using the super element approach (with reflate) with the reference solution (standard simulation)

The details of the CPU time obtained for the present case from a sequential run on a Intel processor with 3.60 GHz clockspeed is shown in the following table:

Table showing CPU time comparison for the standard simulation and a simulation using the super element approach. *Reflate CPU time is calculated as the difference between the present simulation CPU time and the simulation performed in Step02.
