Meeting Your Analysis Deadlines Using ANSYS RSM

October 10, 2014 By: Michael Kuron

As engineering analysts, we've all experienced the dreaded time crunch: your boss or client wants results yesterday and you're still waiting on 10 runs to complete. It's times like these when your computer can't run fast enough! When this situation arises, I usually take the following four steps:

1) Panic!

2) Have a cup of coffee and calm down.

3) Locate all of the computers in the office that are sitting idle (and even some that aren't)

4) Configure ANSYS Remote Solve Manager (RSM) to efficiently complete my analyses

ANSYS RSM is a job queuing system designed specifically for use with the ANSYS suite of solvers. It enables jobs to be offloaded from your local machine and solved on remote compute servers. With RSM, users can pre- and post-process their jobs locally but run the solutions remotely.

There are three main roles in the RSM hierarchy, which are illustrated below. The first role is the RSM Client: your local desktop or laptop from which you want to offload a job to be run. The second is the Solver Manager which acts as a hub that receives jobs from RSM Clients and dispatches them for solving. The final role is that of the Compute Server, which are the machines that the jobs actually run on. The Compute Servers can be any type of machine suitable for an analyses including laptops, desktops, a cluster, or even your bosses' desktop while he's on vacation (just kidding Nick!).

ANSYS Remote Solve Manager Roles

Once RSM is configured, you can set up your analyses to be submitted to a queue on the Solve Manager. As soon as a Compute Server becomes available, the job will be submitted and run. Not only can you run multiple jobs in parallel, they will automatically be queued and submitted as soon as a machine becomes available. As soon as the job completes, the results will be returned to your desktop so that you can post-process them. For example, when working on a CFD consulting project a few years ago, I was able to churn through hundreds of geometric configurations by taking advantage of the seamless integration of ANSYS RSM and ANSYS Workbench. Without RSM, I'd probably still be running those analyses today!
