Overview
FLOW-3D
FLOW-3D gives you a powerful toolset for modeling complex fluid motion with a specific focus on free-surface flows. You can simulate how liquids interact with solid structures, track bubbles or droplets, and analyze thermal effects in high-precision engineering environments. It uses a unique grid-based approach that simplifies your meshing process while maintaining extreme accuracy for moving boundaries and intricate geometries.
You can apply this technology across diverse fields including civil hydraulics, metal casting, and microfluidics. Whether you are designing a dam spillway or optimizing a laser powder bed fusion process, the software provides the physical insights needed to reduce physical prototyping costs. It is designed for professional engineers and researchers who require high-fidelity results for transient, three-dimensional fluid dynamics problems.
SimScale
SimScale is a cloud-native simulation platform that lets you test your designs against real-world physics without expensive hardware.
