As FlowBelow expands its product lineup, it continues to invest in tools that accelerate design and testing.

01
The challenge

Needed scalable and advanced software at an accessible cost.

02
The solution

Implemented Simcenter STAR-CCM+ with expert support from Applied CAx.

03
The impact

Brought CFD in-house, improving collaboration across engineering teams.

Challenge

As a growing startup, FlowBelow needed a software solution that could support its current operations while scaling seamlessly with future growth. The team sought tools that balanced advanced capabilities with accessible pricing.

The start-up package allowed us to try new software that works well for our company and product development efforts.

To accelerate development, FlowBelow turned to Siemens’ startup package.

Solutions

Turning software into a strategic advantage

With Siemens software, FlowBelow faced fewer barriers to growth. The scalable licensing made it easy to expand the number of seats, allowing more engineers to use the tools collaboratively rather than individually. This shift enabled the team to work more efficiently. Software alone was not enough. FlowBelow also needed guidance to implement and optimize Siemens’ software effectively. Applied CAx helped streamline the setup by answering technical questions and providing expert support every step of the way. Applied CAx’s flexibility and responsiveness was invaluable, especially during a period of careful cost management.

Results

Driving innovation with digital tools

By combining Siemens’ advanced simulation software with hands-on support from Applied CAx, FlowBelow is building a more agile and data-driven engineering environment.

With STAR-CCM+, the company has brought computational fluid dynamics (CFD) in-house. This has sped up simulation, design iteration, and validation. FlowBelow continues to expand its digital toolkit, now exploring Nastran FEA to further enhance its analysis and testing capabilities. These digital tools are helping the team collaborate more effectively and innovate with confidence.
