About

FlowSIM Pro makes powerful open source simulation tools accessible to everyone, with OpenFOAM as the CFD core. The focus is on the efficient preparation of building simulations. Developed in practice by engineers who know what matters in everyday project work. Import your BIM and 3D models directly; we significantly simplify the complex setup. Our modern graphics engine renders even large models with exceptional speed and is optimized for multicore processors. Evaluate CFD results directly in FlowSIM Pro, in high visual quality and without external tools like ParaView. With NVIDIA® RTX support for ray tracing and AI denoising as well as LuxCore for physically based rendering, you can combine CFD visualization with architectural rendering for impressive results. Explore your designs in virtual reality with OpenXR support. Runs on Windows and Linux. Need help? Use the built-in AI assistant to validate your simulation setup or get support.
