## 4.5. Fully Automatic Decomposition for Euler/Unstructured

There is an even simpler (and sometimes more efficient) alternative to the method outlined in Decomposing Euler-Lagrange Coupled Problems. Autodyn offers a fully automatic decomposition option for models containing any combination of Euler and unstructured solvers.

When using this fully automatic option there is no further input required by the user in terms of model set-up. On execution the model is automatically decomposed over the number of tasks specified when starting Autodyn. At any point after the model has been initialized the resultant decomposition can be viewed using the Plot parallel decomposition option also found in the Parallel Processing panel.

Load in the model MINPAR from the samples directory within the Workbench distribution.

Select the Fully automatic Decomposition option and run the analysis for 1 cycle with 2 CPU’s defined at start-up. The automatic domain decomposition that has been used can be seen in the picture below.
