Top Hack! Making your elastic units stretch further

We’re all for making cost savings where we can and it’s no different when it comes to Ansys simulation tools. Here, our support engineer Matt Greenslade, gives a step-by-step guide to some of the ways you can use elastic units more efficiently depending on the jobs you’re running.

In Ansys Mechanical…..

Update Projects from the Workbench Page

Workbench doesn’t consume any Elastic Units, so after performing all pre-processor tasks in Ansys Mechanical, close the Mechanical window and solve the job from the Workbench page.

Make sure that you also go to Tools>Options> Mechanical and set the Release License for Prep-post license.

This will save 12 Elastic Units an hour compared to solving with the Mechanical GUI open.

 Mechanical does not have a timeout function, so be sure to close the Mechanical window when you’re not using it so you don’t burn credits unnecessarily!

For Ansys Fluent Users…

Fortunately, Fluent has an idle timeout setting. This is a great way to stop unnecessary credit usage.

This can be done under File>Idle Timeout.

Fluent licensing works slightly differently so you should not be consuming prep-post credits while using the Solution window.

Using Electronics Desktop

Models can be solved without running the Electronics Desktop window. To do this, navigate to the Electronics Desktop Job Submission tool in the Start menu.

Select your prepared simulation, and under Compute resources, add a new node named localhost, with your desired number of cores.

Submit the job and watch the solution using the Monitor tool. This process can also save you 12 credits per hour!

Do you use SpaceClaim? *

Due to a recent change in licensing on the Elastic portal, SpaceClaim now draws the Discovery Modelling License from the Elastic portal by default.

If you’re using the Discovery Simulation functionality this is great, but if you’re just using SpaceClaim for geometry prep, create a new Environment Variable on your computer with

               ANS_MODELER_FLIP_LICENSE = 1

This will change SpaceClaim back to the mode where it draws a SpaceClaim license from the portal, saving a couple of Elastic Units per hour of usage.

To do this open a RUN window from the start menu and run the command

               rundll32 sysdm.cpl,EditEnvironmentVariables

Then create a new variable and set the value to 1.

If you have any questions relating to elastic licensing, don’t hesitate to get in touch with your local EDRMedeso Support Team.

 *Note: this applies only when using the latest version of software. Using with older versions will have the opposite effect and cost MORE credits!
