nTopology 5.30.2

nTopology is pleased to announce the availability of nTopology 5.30.2. This release introduces several powerful new simulation and modeling capabilities, including porous media modeling for heat exchangers and filtration systems, infinite implicit hatching with viewport clipping controls, and an intuitive expression evaluation block for simplified mathematical operations. Additional geometry creation tools have been added for parametric modeling, along with usage improvements and block optimizations to enhance the overall user experience.


Porous Media
The Isotropic Porous Medium Property block enables porous media modeling in nTop Fluids. This property for the fluid attribute is critical for allowing several key, large-scale application cases that were previously out of reach.
- Common applications for the property are:
. Heat Exchangers: Simulating large-scale heat exchangers where explicitly modeling the complex internal geometry is computationally prohibitive.
. TPMS Homogenization: Analyzing the bulk flow of Triply Periodic Minimal Surfaces (TPMS) and other complex lattice structures through homogenization.
. Filter Simulation: Modeling flow through various types of filtration media to predict pressure drop and performance.
- Block Name: Isotropic Porous Medium Property
. Location: Fluids > Material Information
. Permeability: Permeability.
. Forchheimer Parameter: Forchheimer coefficient (non-Darcy permeability).
. Output: Isotropic Porous Medium Property
Infinite Implicit Hatching
- Infinite Implicit Hatching addresses the challenge of visualizing infinite implicit surfaces by introducing viewport clipping controls and visual feedback. This feature helps you work with implicits extending infinitely in one or more dimensions by allowing them to clip these surfaces to the current viewport for better visualization and navigation.
- The new cross-hatch visualization clearly shows clipped regions (green for front faces, blue for back faces), making it easier to understand which portions of infinite geometry have been cut away. You can toggle viewport clipping on/off and update the clipping region as they move around their model.
- If a bounding box is set using “Set Bounding Box”, then that will override the behavior but will still display the cross-hatch visualization if the bounding box clips the geometry.

Evaluate Expression
- The new Evaluate Expression block allows you to write mathematical expressions using familiar syntax instead of having to construct complex calculations using multiple interconnected blocks. This makes creating, reading, and editing engineering expressions easier.
- Block Name: Evaluate Expression
. Location: Math > Utilities
. Expression: Expression to evaluate.
. Dimensionality: A scalar variable representing the expected dimensionality to which the expression should evaluate.
. Variables: A variable to use inside the expression.
. Output: Scalar Field
Point between Points
- The new Point between Points block creates a point linearly interpolated between two points. This is useful for setting up parametric geometry and datums.
- Block Name: Point between Points
. Location: Create > Vectors
. Point 1: First point to be interpolated.
. Point 2: Second point to be interpolated.
. Output: Point
Offset Plane
- The new Offset Plane block creates a plane specified by an offset from another plane. This is useful for setting up parametric geometry and datums.
- Block Name: Offset Plane
. Location: Create > Vectors
. Plane: Plane to offset.
. Distance: Negative or positive distance to offset the Plane.
. Output: Plane
Point in Frame
- The new Point in Frame block creates a point within the local coordinates of a Frame. This is useful for setting up parametric geometry, subsystems, and datums.
- Block Name: Point in Frame
. Location: Create > Vectors
. Description: Create a point at specified local coordinates within a Frame.
. X: Local X component of the Point.
. Y: Local Y component of the Point.
. Z: Local Z component of the Point.
. Frame: Frame in which to create the Point.
. Output: Point
Two Body Field
- The new Two Body Field block creates a linear interpolation field between two bodies. This can be used to create a parameterization field from the surface of one implicit body to another.
- Block Name: Two Body Field
. Location: Fields > Utilities
. Implicit A: The first implicit. Values of the resulting field will be equal to -1 at the surface of this implicit.
. Implicit B: The second implicit. Values of the resulting field will be equal to 1 at the surface of this implicit.
. Output: Scalar Field


Usage Improvements
- Optimization plots are now exposed in the Bottom Panel, where you view tables, rather than the Right Side Panel.
Block Updates
- We have updated Distance to Curve from Axis to remove discretization artifacts and provide a smoother result for downstream lofting operations.
- We have added a new Ray Cast block that now defaults to a Beta Implicit Body overload rather than a Voxel Grid, allowing you to cast straight to implicit geometry without discretizing.
- We have added a new overload to JSON from Dictionary block that accepts a list of Scalar variables as values.


nTopology introduced the concept of implicit modeling for mechanical design, which is an innovative, modern, and scalable way define parts and products. It has many benefits to end-users and companies, such as the elimination of model failures, speed of changes or iterations, and scalability to name a few. But implicit modeling enables so much more. In this informational session, we'll explore a topic that is redefining product development – field-driven design. In short, field-driven design is a way for design, analysis, and manufacturing teams to overlay information into one engineering model. This approach enables orders of magnitude increase in design iteration speed and greatly improves collaboration between teams.

How Field-Driven Design Allows Engineers to Design for Additive Manufacturing


Watch this information session where we'll define field-driven design, show examples of how it enables better knowledge sharing, and show how it promotes the development of more sophisticated, highly engineered products. You'll also better understand how nTopology is addressing today's engineering problems through its nTop Platform product.
nTopology was founded in 2015 to enable engineers and designers to create any geometry — no matter how complex — and meet the requirements of high-performance products.
