This document describes how to run the Ansys Motion™ solver from a command line interface, without using the Ansys Workbench™ application or the Motion Preprocessor.
To run the SMP solver or an HPC solver on a single machine, Motion should be installed. No additional setup is required.
The HPC solver uses Intel MPI. Setting up the environment for MPI execution is done automatically by the run script.
To run the HPC Solver on a cluster machine, the following configuration is required:
All machines must have the Motion executable located at the same path. Install Motion in the same location on each machine, or use a shared drive or symbolic link.
All machines must be remotely accessible and have a shared network folder in the same location for input and output files.
(Linux only) You need to establish a passwordless SSH connection to ensure proper communication for MPI processes. See Get Started with the Intel HPC Toolkit for Linux.
If you are running the solver directly without using the GUI, you must supply the related *.dfs and *.ssc files. See Export Simulation Input Files in the Motion Preprocessor User Guide for more information.
Note:
The Motion solver does not require postprocessing files (*.dfg, *.dfm, *.dfr).
Using an *.dfxml file as an input file is not allowed.
Depending on your model, you may need additional input files, such as the *.dll file used in a User Subroutine or Python script. These files should be located in the same directory as the *.dfs file.
The Motion Preprocessor is not supported on Linux systems. You should copy the input files from Windows.
