ABSTRACT

The Advanced Computational Electromagnetic 3D Parallel (ACE3P) simulation suite is a state-of-the-art multi-physics toolkit designed for virtual prototyping of accelerator and rf components. Leveraging over two decades of development, ACE3P integrates advanced physics modeling, including electromagnetic, thermal and structural modeling, capabilities with scalable numerical algorithms to deliver cutting-edge simulations. The suite, comprised of various application modules for accelerator structure design, optimization and analysis, utilizes higher-order curved finite element methods to achieve high fidelity while enabling fast simulations for large-scale problems. The integration of ACE3P with beam dynamics and radiation transport codes, such as IMPACT and Geant4, supports comprehensive start-to-end simulations for accelerator systems. Simulation workflows on HPC systems have been enhanced through the development of LUME-ACE3P, built on the framework of the LUME project, which streamlines parameter sweeps and optimization tasks. This presentation highlights ACE3P’s recent developments and its performance on large-scale accelerator designs, demonstrating its scalability and efficiency through case studies conducted on NERSC supercomputers.
