nTopology 4.20.2

The Team nTopology is pleased to announce the availability of nTopology 4.20.2. This release features a Natural Frequency Constraint block, making constraining the Topology Optimization in the defined frequency range easier.

nTop 4.20 - What's New

Natural Frequency Constraint
The Natural Frequency Constraint combines design response constraint and natural frequency response. This block makes it easier for you to constrain the topology optimization to generate shapes with natural frequencies inside or outside the specified range.
Block Name: Natural Frequency Constraint
Location: Optimization > Constraints
Description: Define a natural frequency constraint for optimization to generate shapes with natural frequencies that lie inside or outside the specified range.
- Number of Modes: Number of modes that will be searched for and included in the constraint computation.
- Band Type: This defines whether the natural frequency of the optimized shape lies inside or outside the range defined by the Min Frequency and Max Frequency inputs.
- Min Frequency: The lower bound of the natural frequency range.
- Max Frequency: The upper bound of the natural frequency range.
- Load Case: Load case for the constraint.
- Output: Optimization Constraint
The image below shows an example of avoiding any modes from 7500Hz (Lower Bound) to 25000Hz (Upper Bound)


Usage Improvements
We added a new Recent Files tab in the Welcome Screen.


Block Updates
We have updated the FE Region and FE Boundary types to include "fe mesh" in the properties panel to access the selected mesh region and "parent mesh" to access the entire mesh used to select the boundary.


We have updated the Point Force and Point Moment blocks to include the Rigid (RBE2) or Flexible (RBE3) Connector input.


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.
