nTopology 引入了机械设计的隐式建模概念，这是一种创新、现代且可扩展的定义零件和产品的方式。它为最终用户和公司带来了许多好处，例如消除模型故障、更改或迭代的速度以及可扩展性等等。但隐式建模实现的功能远不止于此。在本次信息会议中，我们将探讨一个重新定义产品开发的主题 – 现场驱动型设计。简而言之，现场驱动型设计是设计、分析和制造团队将信息叠加到一个工程模型中的一种方式。这种方法使设计迭代速度提高了几个数量级，并大大改善了团队之间的协作。nTopology is pleased to announce the availability of nTopology 5.23.2. This major release features one of our most anticipated new nTop Fluids toolsets, bringing CFD into the iterative computational design loop. We also have new blocks to allow more nTop modeling. nTop 5.23 - What's New nTop Fluids
- nTop Fluids is a new computational fluid dynamics (CFD) toolset integrated directly inside nTop. Eliminating the meshing and solving bottlenecks created by traditional tools, nTop Fluids brings CFD into the iterative computational design loop.-
- Workflows where you could use nTop Fluids:
. Internal flow for heat exchangers, manifolds, and valves
. Rapid iteration with GPU-solver and simplified meshing
. Creation of training datasets for machine learning
- You can access all the new toolset by enabling Beta and navigating to the new Fluids [Beta] ribbon.
Flow Analysis
- Calculates the pressure and velocity on a Virtual Model. The solution uses the Lattice Boltzmann Method.
- A transient simulation is initiated and continues until the flow reaches a statistically steady state, returning time-averaged pressure and velocity fields.
Note: This block needs an NVIDIA GPU to run- Location: Fluids [Beta] > Analysis
. Virtual Model: The Virtual Model represents the fluid domains to be simulated.
. Boundary Conditions: The Boundary Conditions to be used for the analysis. At least one Pressure and one Velocity Boundary condition are required.

Isotropic Fluid Property

Velocity

- Location: Fluids [Beta] > Utilities
. Result: The result from which to extract boundary values.
. Property Field: Property field from Flow Analysis.

Point along Curve
- The Point along Curve block creates a point at a specified distance along a curve.
- Location: Create > Curves
. Curve: Curve along which to create a point.
. Distance: Distance along the curve to create the point. If this value is outside the range from zero to the length of the Curve, the point will be extrapolated. The extrapolation will be linear for Lines and Splines, and circular for Arcs. If Curve is a Polycurve, the extrapolation will be based on the type of segment at the corresponding endpoint.

Usage Improvement
- We have introduced a new Streamlines visualization, which enables you to intuitively view the CFD results.
. View Settings is accessible in the Display tab of the Right Panel.
. Seed count controls the number of streamlines. Increase the seed count for denser streamlines.
. Specify Seed enables you to select a seeding region with the adjustable center point and radius.
- We have updated the color of the blocks that output the Vector Field type to match that of the Scalar Field type.
Block Updates
- We have updated our simulation blocks to be compatible with different solvers in nTop. We have also updated the older Simulation ribbon to be Structures to align with the new simulation capabilities of nTop. Many blocks have also been updated with name changes, input/output type changes, or both, but their behavior has not changed. This support article lists all the blocks and toolkit blocks that have been updated with more information regarding this update.
- We updated the Field Optimization block to fix an issue that caused the Min Infill thickness to differ when results converged.
