CONTEXT
Wideband Radio Frequency (RF) Devices for space applications require demanding and time-consuming RF simulations through the Finite-Difference Time-Domain (FDTD) method and Thermomechanical topology optimization.
Standard methods with limited computational power set a constrain to the mesh accuracy, besides a long design phase. Thermomechanical design is generally handled separately from the RF design. Additional prototyping is necessary to guarantee performance during a product development, further increasing development time and costs.
OBJECTIVES
HoRuS – HPC for RF Subsystems experiment focuses on leveraging High Performance Computing (HPC) to optimize Radio Frequency (RF) subsystems. The goal is to improve the performance and efficiency of RF devices through advanced simulations and predictive modelling, utilizing high computing power.
In this experiment, applications involve the design, fabrication and testing of complex RF components used in telecommunications, radar, and space communication systems. By adapting a Multiphysics simulator used in the design phase for compatibility with HPC, the time required for the development and optimization of these systems is significantly reduced, improving both accuracy and speed in design processes.
This HoRuS project aims at the experimental verification of the benefits of HPC in streamlining the conception and development of RF filters and antennas.
RESULTS
The HoRuS experiment developed an HPC-based simulation workflow to improve the design of RF filters, antennas and subsystems for space applications. The solution combined Open Engineering’s simulation platform with two complementary tools: OOFELIE for thermomechanical optimisation and cuFDTD for electromagnetic analysis. Both software environments were adapted to run on the Leonardo HPC infrastructure, including the development of a new multi-GPU version of the electromagnetic solver.
Using HPC made it possible to distribute simulations across up to four GPUs within a compute node, overcoming memory limitations of standard workstations and enabling much larger and more detailed models to be analysed. The output of the experiment was a scalable digital design workflow capable of running high-fidelity multiphysics simulations in half the previous time, supporting faster optimisation, better engineering decisions, and future development of more complex RF products.
