Overview
Diabatix ColdStream
ColdStream is a cloud-native platform that transforms how you approach thermal management and cooling challenges. Instead of manually iterating through designs, you define your boundary conditions and let the generative design engine create optimized cooling structures for you. It handles everything from liquid cooling and heat sinks to complex battery thermal management systems, ensuring your components stay within safe temperature limits while minimizing pressure drop and material use.
You can move from initial concept to a high-fidelity, manufacturable design in a fraction of the time required by traditional CFD methods. The platform is built for engineers in industries like automotive, aerospace, and electronics who need to solve extreme heat dissipation problems. By moving your thermal simulation to the cloud, you eliminate the need for expensive local hardware while gaining access to powerful optimization algorithms that explore design possibilities you might never have considered manually.
SimFlow
SimFlow is a powerful computational fluid dynamics (CFD) platform that brings the capabilities of OpenFOAM to a user-friendly graphical interface. You can handle complex engineering challenges including compressible and incompressible flows, heat transfer, and chemical reactions without writing code. It allows you to import geometry directly from CAD software, create high-quality meshes, and monitor simulations in real-time to ensure accuracy and efficiency.
Whether you are designing automotive components or optimizing HVAC systems, the platform provides the tools to visualize flow patterns and pressure distributions effectively. You can run simulations on your local machine or scale up to high-performance computing clusters for massive datasets. It is designed for engineering professionals and researchers who need the precision of open-source solvers combined with the speed of a modern, intuitive workflow.
