  • Accelerating Simulation with Amazon Web Services High-Performance Computing

    with Gaurav Mishra and Sandeep Aggarwal, Amazon Web Services

    Modern multiphysics simulations are becoming increasingly complex, requiring greater computational resources to solve large models with coupled physics, fine meshes, and extensive parametric studies. As model size and complexity continue to grow, reducing simulation turnaround time becomes essential for efficient engineering design and research.

    The COMSOL Multiphysics® software addresses these challenges through shared-memory and distributed-memory parallel computing, allowing simulations to scale from multicore workstations to high-performance computing (HPC) clusters. Recent updates further extend the performance capabilities of COMSOL® with GPU acceleration through the NVIDIA CUDA® direct sparse solver (NVIDIA cuDSS), providing another option for accelerating computationally intensive simulations. Amazon Web Services (AWS) complements these capabilities by offering on-demand CPU and GPU resources, enabling users to run larger models without investing in dedicated HPC infrastructure.

    In this workshop, Sandeep Aggarwal will demonstrate how to deploy and run COMSOL models on AWS HPC infrastructure. The session will cover cluster deployment, distributed-memory execution, GPU acceleration, job submission, and performance optimization. Benchmark examples comparing a local workstation with AWS HPC resources will illustrate how cloud HPC, combined with the latest capabilities in COMSOL Multiphysics®, can significantly reduce solution times and enable the setup and solving of larger, more demanding multiphysics simulations.

    • Time- and frequency-domain modeling of RF and microwave systems, for analyzing phased antenna arrays, 5G millimeter-wave filters, and connectors; coupled multiphysics effects such as EM heating and structural deformation

    • Ray tracing methods for optical systems, plus structural-thermal-optical performance (STOP) analysis for systems in extreme conditions (e.g., space); multiscale approaches that bridge ray and wave optics

    • Full-wave EM simulation of optical and photonics devices, i.e., filters, sensors, plasmonic structures, and metasurfaces; the beam envelope method; multiphysics couplings for stress-, electro-, acousto-, and magneto-optical effects

    Attend this minicourse to gain a broad overview of the electromagnetic and optical simulation capabilities of the COMSOL® software.

  • The meshing step in the modeling and simulation process directly influences the accuracy, computation time, memory requirements, and solution interpretation of a simulation. COMSOL Multiphysics® offers fully automated meshing that accounts for both geometric information, such as surface curvature, and settings for the modeled physics phenomenon. For example, the software can automatically adapt the mesh size to resolve wave propagation problems or use boundary layer meshing for walls in CFD.

    The automatic meshing functionality is complemented with powerful yet user-friendly meshing functionality for manipulating a mesh generation sequence to create a mesh of your choice. For instance, you can create a hexahedral mesh for one subdomain and tetrahedral or prismatic meshes for other subdomains.

    Attend this minicourse to learn a set of best practices for custom meshing and mesh import. We will demonstrate the workflow for custom meshing as well as how to use, repair, and modify imported meshes generated with other software. Import of STL, PLY, and 3MF files will be covered.
