Overview
nanoCAD
nanoCAD provides you with a high-performance CAD environment that feels instantly familiar if you have ever used traditional drafting software. You can create complex 2D drawings and 3D models using a native DWG format, ensuring your files remain compatible with partners and clients without data loss. The platform is designed to handle large-scale projects efficiently, offering a professional toolset for engineers, architects, and designers who require precision and reliability.
You can customize your workspace with an open API and specialized modules for mechanical design, construction, and topography. Whether you are drafting simple floor plans or developing intricate mechanical components, the software provides the speed and accuracy you need. It serves as a cost-effective alternative for teams of all sizes, from solo freelancers to large engineering firms, by offering flexible licensing options that fit your specific budget and project requirements.
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.
