Overview
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.
SimScale
SimScale is a cloud-native simulation platform that lets you test your designs against real-world physics without expensive hardware. You can run complex fluid dynamics, structural analysis, and thermal simulations directly in your web browser. This eliminates the need for high-performance local workstations or complex software installations, allowing you to iterate on your engineering projects faster and more efficiently.
You can collaborate with your team in real-time on shared simulation projects, making it ideal for distributed engineering departments and consultancies. Whether you are optimizing a building's ventilation or testing the structural integrity of a mechanical part, the platform provides the computational power you need on demand. It scales with your project requirements, offering a range of specialized tools for electronics cooling, rotating machinery, and urban microclimate analysis.
