Cadence Design System has announced that it has acquired Pointwise a specialist in mesh generation for computational fluid dynamics (CFD). The addition of Pointwise’s technologies and experienced team supports the Cadence Intelligent System Design strategy and further broadens its system analysis portfolio, complementing the recently acquired NUMECA CFD technology.

Together, these acquisitions will enable advanced CFD solutions where accuracy, reliability, predictability and performance are paramount for high-fidelity characterisation of fluids, such as air flowing over an airplane.

Pointwise’s mesh generation technology addresses the high-growth pre-processing CFD market sub-segment. The acquisition builds on the recent NUMECA acquisition and Cadence’s innovative multiphysics products including the Clarity 3D Solver for electromagnetic (EM) simulation, the Clarity 3D Transient Solver for finite difference time domain (FDTD) system-level EM simulation and the Celsius Thermal Solver for electrothermal co-simulation.

Pointwise’s technology adds world-class mesh generation and pre-processing capabilities that read data from all of the leading CAD formats and export data to over 40 CAE formats. Pointwise’s core competency in robust grid generation squarely addresses the aerospace industry’s demand for high-fidelity discretisation of aircraft geometries.

Pointwise’s technology creates multiple mesh types to provide the level of control needed to ensure converged and accurate CFD results. In addition to automation and ease of use being paramount for the widespread adoption of CFD, it is imperative to generate sophisticated meshes that adhere to stringent accuracy requirements. Pointwise’s proven technologies are used by leading organisations such as Hermeus, senseFly and ONERA to enable purpose-built mesh for applications including drag prediction and internal flows through exhaust manifolds.

“Cadence’s computational software expertise and expanding multiphysics portfolio are accelerating digital wind tunnel experimentation for the aerospace industry,” said Tom Beckley, Senior Vice President and General Manager of the Custom IC & PCB Group at Cadence. “The acquisition of Pointwise’s proven CFD meshing technology catapults Cadence into a leadership position by addressing critical complexities in the analysis workflow, giving engineering teams rapid insight, predictability and high accuracy of their system design well before physical production.”

“Pointwise is dedicated to delivering industry-leading mesh generation capabilities,” said John Chawner, President of Pointwise. “We are very excited to enhance Cadence’s CFD strategy with our deep meshing expertise and talented team. The combined technologies of Cadence, NUMECA and Pointwise significantly expand Cadence’s CFD and electromechanical analysis solutions, customer base and engineering talent.”

The terms of the transaction were not disclosed. The acquisition is expected to be immaterial to revenue and earnings this year.
