Welcome to nTop’s Flow Analysis course! Flow Analysis is a subset of nTop Fluids, a new computational fluid dynamics (CFD) toolset integrated directly in nTop. CFD has traditionally been a specialized discipline requiring dedicated software systems separate from your design environment. Traditional CFD workflows are plagued by bottlenecks that can severely impede design exploration. By embedding Flow Analysis within nTop, we empower designers to:
Meshing complex domains for exporting to CFD solvers demands substantial computational resources, with each iteration requiring intricate mesh regeneration. Instead, perform flow analysis directly on implicit bodies, nTop’s native geometry.
Solve times can stretch from hours to days, creating lengthy waiting periods between design iterations. Additionally, large-scale simulations often face resource limitations, such as insufficient computing power and parallel inefficiencies. These challenges can hinder the performance and scalability of simulations.
nTop’s Flow Analysis uses Lattice-Boltzmann algorithms, well suited for complex geometries and nTop’s ability to leverage modern, GPU-based computing architectures.
Iterative design involves preparation, simulation, interpretation, and refinement along each step, allowing engineers to progressively explore a wide design space and understand the nuanced impacts of parameter adjustments.These constraints have long been a critical pain point in CFD, restraining the full potential of design optimization. This disconnected process creates significant friction and delays in the design cycle, often taking days or weeks to complete single design iterations.
The seamless integration of CFD into nTop means fluid simulations can happen within the same environment as your design work, creating a truly iterative process without the traditional barriers between CAD modeling and CFD analysis.
These advantages combine to support rapid iteration and allow thorough exploration of design spaces, empowering engineers to approach optimal solutions that may have remained undiscovered with conventional methods.
Note: Flow Analysis in nTop requires an NVIDIA GPU.
