Questions and answers about STAR-CCM+

How do I get started with using Simcenter STAR-CCM+ ?

Before you start simulating multi-regime and use Simcenter STAR-CCM+  to assess your product design’s real-world performance, Volupe takes you through a three-stage process to introduce you to the broad range of CFD simulation tools.

  • Initial stage

First, we’ll define your engineering teams’ challenges and uncover what problems you would like to solve with Simcenter STAR-CCM+  software. We’ll introduce you to our simulation engineers’ and our team will share expertise and knowledge relevant to your industry.

Following our first meeting, our simulation engineers will demonstrate how Simcenter STAR-CCM+ ‘s design space, multiphase flows, and CFD simulation tools can aid your design exploration without using physical prototypes and testing environments to collect data.

  • Evaluation stage

We’ll work with you to create an evaluation plan where we’ll identify cases to complete during the evaluation. Once our evaluation plan is set, our team will work with you to set clear goals and ROI objectives.

Next, our team and simulation engineer will customize your training based on your experience and industry. We’ll provide and install an evaluation license to cover 1-2 months (depending on the scope) and schedule weekly technical stand-up meetings to offer ongoing support during the evaluation stage.

At the end of the evaluation period, we’ll review the results and measure them against the goals and objectives defined earlier in the process.

Implementation stage

Implementation stage

Based on the outcome of the evaluation process, we provide a customized solution with Simcenter STAR-CCM+  software to meet your engineering teams and entire organization’s needs.

Following acceptance of the recommended Simcenter STAR-CCM+  software solution, we’ll complete the procurement process and provide a complete solution. Usually, getting your CFD simulation software up and running takes 2-3 working days from order to installation. We’ll support your engineering teams and provide assistance with your CFD simulation solution installations.

As a Volupe customer, you will have a dedicated application support engineer who is your first point of contact should your team have any questions. We’ll conduct bi-annual customer success meetings to discuss your customized simulation solution and overall satisfaction with the CFD software.

How to use Simcenter STAR-CCM+ for design exploration?

Simcenter STAR-CCM+ offers powerful capabilities for design exploration, enabling you to follow unique models relative to your objectives. A general workflow could look like this: Defining design variables and identifying the parameters that you want to vary in your design exploration. This can be achieved using the built in Design Manager.

Then set up and create a new design exploration study, specifying where you want to optimize designs, i.e. minimizing drag or heat transfer. Choose the opitmization algorithm (genetic algorithms, particle swarm optimization, or gradient-based methods). From here, you can define design points and specify how these will be generated.

In this flow example, the next step would be to set up and run simulations, which you can do in parallel with Simcenter STAR-CCM+, and analyze your results. Then based on this analysis, you can refine and repeat. As a final step you can also validate and verify the selected design(s) using additional simulations or physical testing, if necessary.

How to create simulation model with Simcenter STAR-CCM+ ?

Simcenter STAR-CCM+ offers a wide range of capabilities, and the specific details of creating a simulation model may vary depending on the type of simulation, physics models, and analysis objectives.
