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.
Windographer
Windographer is the industry-standard tool for analyzing wind resource data. Whether you are working with data from met towers, SoDAR, or LiDAR systems, you can quickly import raw files and perform complex quality control. The software automatically identifies data gaps and anomalies, allowing you to flag or filter them with a few clicks. You can then generate high-quality graphs and tables to visualize wind shear, turbulence intensity, and energy production potential.
You can use the platform to streamline your entire pre-construction wind assessment process. It handles massive datasets with ease and allows you to export cleaned data directly into wind flow models like WAsP or WindSim. By automating repetitive data cleaning tasks, you save hours of manual work while ensuring your wind resource assessments are accurate and bankable.
