A next-generation CFD solver

We are building a new CFD solver written from the ground up integrating novel machine learning research and modern numerical programming approaches. Deployed through a web application and API gateway.

Featuring:

  • Order of magnitude efficiency gains
  • Native deployment to cutting-edge hardware accelerators: GPUs, TPUs
  • Adjoint methods for arbitrary optimisation targets

Expensive simulations bottleneck product development

To reduce reliance on expensive physical testing, engineers lean heavily on CFD to optimise their designs. However, many problems across aerospace and automotive are extremely computationally expensive to simulate, taking from hours to days to run; critically slowing product development.

By developing an order of magnitude more efficient CFD solver, we will dramatically increase the productivity of engineers. This will allow engineers to efficiently search for optimal designs and therefore develop better products.

 

The Team

Our team combines deep expertise across applied maths, machine learning and software engineering.

Mathematical Engineer

Previously: KCL, University of Oxford

Dr Roy joins us from her postdoc at the Oxford Department of Computer Science where she ported cardiac simulation code to run on GPUs.

She did her PhD at King's College London developing a pipeline to identify fibrosis in cardiac walls from MRI images and simulate the electrical activity behind atrial fibrillation.

She brings her knowledge of GPU computing and machine learning to improve our solver capabilities.

About us

f1_shot_trimmed

Laurence and Michael met at the particle accelerator Diamond Light Source as summer students in 2016, and have been friends since. They moved in together to found Vanellus in the summer of 2022.

They kicked off the business by going through Entrepreneur First, going on to raise a preseed investment round in 2023.

Aditi joined the team in September 2023, and we are hard at work building out our core CFD solver, with the goal of launching in spring 2024.
