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.
SkyCiv
SkyCiv is a cloud-based structural analysis and design platform that lets you work from any device without installing heavy desktop software. You can model, analyze, and design structures ranging from simple beams to complex 3D frames and trusses directly in your web browser. The platform integrates seamlessly with international design codes, allowing you to perform checks for steel, concrete, wood, and cold-formed sections with automated report generation.
By moving your engineering workflow to the cloud, you can collaborate with your team in real-time and access your projects from anywhere. It solves the problem of expensive hardware requirements and rigid licensing, making it a flexible choice for solo engineers and large firms alike. You can also automate repetitive modeling tasks using their powerful API, significantly cutting down your project turnaround time.
