Overview
IronCAD
IronCAD provides you with a flexible 3D design environment that breaks away from the constraints of traditional history-based modeling. You can move, resize, and manipulate parts instantly using the TriBall visualization tool, which simplifies complex positioning and alignment tasks. By utilizing both the ACIS and Parasolid modeling kernels simultaneously, you gain the ability to handle complex geometry without the typical regeneration errors found in other platforms.
You can seamlessly transition between 2D sketches and 3D models to create detailed production drawings and assemblies. The software is specifically designed for mechanical engineers and industrial designers who need to iterate quickly on custom machinery or modular equipment. Whether you are creating one-off prototypes or managing large-scale industrial assemblies, you can drag and drop pre-defined shapes from catalogs to build your designs faster.
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.
