Checklist for Getting the Most Out of Your 30-Day Evaluation

Prerequisites

  • PLATFORM SUPPORT.  Verify that the computer you plan to run the evaluation on is one of the following: 
    • 32-bit/64-bit Windows (XP, Win7, Win8)
    • 32-bit/64-bit Linus (RHEL 5.X)
  • JAVA SUPPORT.  The ADS Workbench requires Java 1.6 or greater.
  • MPICH2 SUPPORT.  You'll need to have MPICH2 installed on your system for parallel execution.  A link to the MPICH2 download is provided as part of our standard installation process.

Tip 1: Define success criteria and use it to drive your plan

Establish success criteria up front and use it to identify the cases you'll want to run during the evaluation.  Make sure that you have at least one test case with good measured data to compare the ADS results against.

Here are some examples of the types of questions our clients consider as they undergo an evaluation:

Accuracy

  • Does the system consistently discern a design improvement from a design mistake?
  • Do the results map well to measured data?

Robustness

  • How hard is it to generate a quality mesh suitable for input to the solver?
  • How well is the mesh generator able to handle the range of designs we have?
  • How sensitive are the results to the expertise of the user?

Turnaround Time

  • How long does it take to generate a quality mesh?
  • How long does it take to complete a steady run?
  • How long does it take to complete a time accurate run?

Ease of Use/Integration

  • How hard is the system to learn?
  • Can the system be easily integrated into my design system?

Design Impact

  • Will the system help me to meaningfully improve my designs before committing to hardware?
  • Will the system enable new analysis capabilities that can address issues of import to my company? 
  • Will the accuracy and speed of the system allow my company to reduce the number of redesigns we typically do during product development?  
  • How much can my company save in time, tooling costs and rig test costs for each redesign cycle that can be eliminated?

Most clients start with 3D steady analysis to compare CFD results against measured data.  We encourage you to also try time accurate analysis to give you a sense for the new insights that can be gained and the speed at which the results can be delivered.

Tip 2: Start with the ADS Workbench  

Whether you're a novice or a power user, the best way to get your evaluation rolling is to use the ADS Workbench.  In the workbench you'll have access to technical and user documentation, sample cases, wizards to help you set up your simulation runs and file management to keep your case files in order.  

There are two ways to get familiar with the ADS Workbench.  If you like reading manuals, then click on the "take a tour" option when you open up the workbench for the first time.  This will take you to the "Workbench Fundamentals" section of the documentation.  

Not a big fan of manuals?  Then check out the ADS Workbench series of video tutorials at ADS University.  

Tip 3: Provision your evaluation license

You'll need to request and install licenses before being able to use your evaluation copy of the ADS system.  This involves running a license request executable, sending the resulting information to This email address is being protected from spambots. You need JavaScript enabled to view it. , and installing the received licenses in the proper directory location.  

Tip 4: Show control parameter values in the case wizards 

There is an option in the ADS Workbench to show the control parameter names and values when you're setting up a case.  This helps aspiring power users to associate the questions and answers in the wizards to the actual control parameter names and values in the setup files that are ultimately generated.  

Go to the Windows>Preferences>Wizards and check the box to show control parameter names and values in drop down selections.  

Tip 5: Try out the sample cases

We strongly recommend that you check out and run the included sample cases before you start configuring your own runs.  There are two reasons for this: (1) you can use these cases to verify that serial and parallel execution is working properly; (2) the cases will give you concrete examples for how to properly set up your ADS runs.

We provide samples for all of the simulation types you can run in the workbench, including 2D cascade runs, 3D single row steady runs, 3D multi-row steady runs and 3D multi-row time accurate runs.  We've also included a centrifugal compressor case to show you how to set up a run with a main blade and splitters.

Tip 6: Base your first cases on sample cases

It's always easiest to set up your first case based on one that you know already works.  This can be done very easily using the workbench.  When you create a new case, simply check the box that allows you to create a new case from an existing one and specify the sample case you want to use.

Note: the sample cases needed to be loaded into your workspace before they can be used as templates.  

Tip 7: Leverage the ADS Support Portal

If you're conducting an evaluation, all support is handled through the support portal.  Use the federated search function to search for answers to your questions, or pose new questions or feedback in our discussion forums.
