The following commands will stop the ANSYS CFX solver at the end of the next timestep and the solver will write a result file (res file). The solver runs in the “runtime” directory, e.g. example_001.dir. You can stop the solver by cfx5stop -dir -dir Name of directory in which the ANSYS CFX Solver is running. When the supplied directory is the the overall run directory for a multi-configuration or operating point case, prevent the run from starting new configurations or individual operating points, but allow running configurations or operating points to complete. E.G: cfx5stop -dir example_001.dir Alternatively you can use the following Unix command on Linux to create the file “stp” in the runtime directory, which will have the same result as using cfx5stop: touch example_001.dir/stp On Windows, the equivalent command would be: type nul > example_001.dir/stp Saving a backup You can use the following Unix command on Linux to create the file “trn” in the runtime directory, which will save a backup file. Creating a “bak” file in the runtime directory will also save a backup file. touch example_001.dir/trn OR touch example_001.dir/bak On Windows, the equivalent command would be: type nul > example_001.dir/trn OR type nul > example_001.dir/bak
