### 3.2.1. Recover Original Session

When opening a CFX-Solver input file, the option Recover Original Session can be used to find the location of the original CFX Case file (that was used to generate the CFX-Solver input file) and load it. Using this option enables CFX-Pre to access more information (such as composite regions, unused materials and meshes, layouts, and views) and then write that information to the CFX-Solver input file.

When the Recover Original Session option is selected, the Replace Flow Data option is available. This will extract the CCL from the CFX-Solver input file and replace the existing Case file data. This is useful to recover the problem definition when it has been modified outside of CFX-Pre during the run.
