Upstream Applied Science Ltd was founded in the United Kingdom in 2019 to offer applied science and maths consultancy services and specialised CFD capabilities.

Mathematical modelling and computer simulation can add significant value to your business, but can be tricky to implement effectively. We use our experience of developing and applying these techniques across a wide range of industries and sectors to generate the right approach for your business, so that you can see the value of these tools without the headaches.

We develop and apply open source toolsets in the computer-aided engineering space and employ cloud computing capability to enable the use of more advanced computational techniques in product design and development, helping you to reduce costs, move faster and design better.

We are passionate about solving business and technical challenges using the broad range of opensource toolsets available.


We would love to discuss how we can help you. Get in touch today!
