SimScale and nTop Announce Integration, Enable Implicit Geometry Import

This week, SimScale announced an integration with nTop, making it possible to import nTop models into SimScale.

SimScale, a cloud-hosted engineering simulation platform, offers fluid dynamics, structural mechanics, thermodynamics, electromagnetics, and multiphysics simulations, accessible from a browser. nTop is known for its implicit-modeling kernel, reported to make modeling complex, unorthodox structures faster. Because of its ability to produce dynamic and scalable lattice structures, nTop has found a robust following in the Additive Manufacturing (AM) space.

According to SimScale's announcement, "By eliminating the traditional bottlenecks of CAD conversion and surface meshing, this workflow opens the door to broader design exploration and innovation for complex DfAM [Design for AM] products."

nTop is integrated with numerous CAD and AM print-preparation software, including those from Autodesk, Materialise, Hexagon, and EOS. The latest arrangement with SimScale expands this list, bringing nTop's modeling functions into simulation.

"Traditional CAD-to-simulation workflows have always been a major bottleneck in high-performance heat exchanger design—you're constantly dealing with meshing failures and geometry conversion issues that kill iteration speed," said Bradley Rothenberg, cofounder and CEO of nTop. "This native integration with SimScale eliminates that friction -- Engineers can now move directly from nTop implicit geometry into a robust thermal and flow solver without the preprocessing headaches, enabling teams to iterate faster and explore design spaces that were previously impractical to simulate."

Complex lattice structures are usually imported into CAD and simulation programs as mesh models, made of micro surfaces. This method reduces the original geometry's mathematical integrity. The ability to import them as implicit models eliminates the need to use mesh models. 

SimScale is touting the new nTop import function as a "streamlined, high-fidelity simulation workflows that enable faster iteration, deeper design exploration, and better-performing heat exchangers."
