### 3.2.20. CFX Multi-Configuration Results File

The CFX-Solver will generate a results file with a name based on the CFX-Solver Input file. For example, running the CFX-Solver using the input file named `file.mdef` in a clean working directory will generate the multi-configuration results file named `file_001.mres`.

For multi-configuration simulations, the CFX-Solver Input and CFX-Solver Results files are very similar; both are small files that contain only high level information about the simulation. In particular, the results file contains:

- Global information about the simulation’s overall definition (such as `Library CCL`, configuration definitions and sequencing, etc…)

- Information about the configuration files (`*.cfg`, which contain configuration specific settings and meshes)

- Information about the CFX-Solver Results files (for details, see CFX-Solver Results File) generated for each configuration step.

CFX-Solver Output and CFX-Solver Results files for each configuration (and configuration step) executed are contained within the multi-configuration simulation’s run directory. For example, running the CFX-Solver using the input file named `file.mdef` in a clean working directory will generate a file and directory structure similar to the following:

- file_001.mres

- file_001.out

- file_001/

  - Configuration1_001

  - Configuration1_001.out

  - Configuration1_001.res

  - Configuration1_002.out

  - Configuration1_002.res

  - Configuration2_001

  - Configuration2_001.out

  - Configuration2_001.res

In this case, the directories `file_001/Configuration1_001` and `file_001/Configuration2_001` each contain the transient and backup files created during the respective configuration runs.
