SimScale has added a new native integration with nTop that allows the import of implicit geometry representations directly from nTop into SimScale, unlocking what it claims as unprecedented speed and robustness in the simulation and design exploration of high-performance heat exchangers.
By eliminating the traditional bottlenecks of CAD conversion and surface meshing, the new capability will significantly accelerate simulation of full-fidelity flow and thermal behaviour in complex, performance-critical heat exchanger designs.
SimScale’s new functionality has been built in close collaboration with nTop, with the goal to allow engineers to work directly with implicit models in its cloud-based simulation software.
Conjugate heat transfer (CHT) simulations are powered by SimScale’s immersed boundary method (IBM), which natively handles implicit geometries without requiring any conversion or geometry discretisation.
Both parties state that the result is a more streamlined, high-fidelity simulation workflow that allows faster iteration, deeper design exploration and better-performing heat exchangers. The value of this capability has already been demonstrated at customers such as Siemens Energy, which SimScale says is using its tools to simulate high performance heat exchanger performance.
“Traditional simulation pipelines struggle with the complexity of high-performance heat exchanger geometries because they require faceted CAD data, which is a time-consuming step,” said SimScale product manager Alexander Fischer. “With this new integration, engineers can move from design to simulation in a fraction of the time, much more reliably.”
nTop CEO Bradley Rothenberg added that the traditional CAD-to-simulation workflows have always proved a major bottleneck for high-performance heat exchanger design. “You’re constantly dealing with meshing failures and geometry conversion issues that kill iteration speed,” he said.
“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.”
All SimScale users, including Community users and Professional license holders, can now take advantage of this new capability.
