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.
Unreal Engine
Unreal Engine provides you with a complete suite of creation tools for developing real-time 3D content. Whether you are building a high-fidelity AAA game, a cinematic film, or a complex architectural visualization, you can manage the entire production pipeline within a single environment. You get access to a powerful world-builder, advanced lighting systems, and a robust physics engine that brings your creative visions to life with stunning realism.
The platform is designed to scale with your ambitions, offering a flexible environment that supports everything from solo indie projects to massive enterprise simulations. You can take advantage of the source code access to customize the engine to your specific needs. With a vast marketplace of assets and a global community of creators, you have the resources necessary to solve complex development challenges and accelerate your project timelines.
Overview
SimFlow Features
- Mesh Generation Create high-quality hex-dominant meshes automatically for complex geometries using the integrated snappyHexMesh and cfMesh tools.
- Multiphase Flow Simulate interactions between different fluids, such as water and air, to predict cavitation, splashing, or free-surface movements.
- Heat Transfer Analyze conduction, convection, and radiation within your designs to optimize cooling systems and thermal management strategies.
- Real-time Monitoring Track residuals and physical quantities during the calculation process to catch errors early and save valuable computing time.
- Parallel Processing Speed up your simulations by distributing the workload across multiple CPU cores with seamless MPI support.
- Post-processing Visualize your results with integrated ParaView support to create stunning animations and detailed vector plots of fluid behavior.
