Learn the fundamental workflow of COMSOL Multiphysics®. This introductory demonstration will show you all of the key modeling steps, including geometry creation, setting up physics, meshing, solving, and evaluating and visualizing results.
COMSOL Multiphysics® version 6.3 provides specialized new features for geometry creation, meshing, and CAD integration, improving the efficiency of model setup. Automatic detection and removal of small details and gaps in CAD models enable more robust mesh generation and efficient models. A new mesh element sizing algorithm ensures accurate resolution of geometric features. Physics-controlled meshing now supports imported STL files, and enhanced operations such as edge extrusion and revolutions improve flexibility in geometry creation. Additional new functionality includes virtual operations for face merging as well as easier swept meshing.
Important updates for the add-on products featuring CAD functionality include the ability to select specific components from assemblies, create variable radius and constant width fillets, and project edges to faces.

Dr. Abhijit Bhattacharyya, Bhabha Atomic Research Centre
Superconducting nanowire-based single-photon detectors (SNSPDs) are of immense importance in experiments for detecting low number photon flux, such as dark matter detection, in addition to using quantum cryptography-based encoded signal transfer and detection. The design strategy uses superconducting nanowires operating near superconducting threshold temperature. Due to the incident photon, the wire trips out of the superconducting zone, and the signal is caught. Further, proper selection immediately brings the wire back to the superconducting state. The RF Module in the COMSOL Multiphysics® software can be used to understand the mechanism and optimize the dimensions of different parts of the detector. In this talk, Dr. Abhijit Bhattacharyya will present a preliminary design concept of this research using COMSOL®.
COMSOL Multiphysics® version 6.3 introduces a range of new features and improvements for electrochemical and chemical reaction engineering simulations. For battery design, the release includes a new two-electrode lumped model and single-particle electrode options, extending the capabilities for simplified and lumped model analysis of battery performance and behavior. Additionally, a demonstration app for analyzing battery test cycles features new functionality for time-dependent surrogate modeling. Furthermore, modeling of concentrated electrolytes in electrochemical cells is now available in all electrochemistry products.
In chemical reaction engineering, new capabilities for simulation of precipitation and crystallization enable users to model particle nucleation and growth while accounting for particle size distributions. A new tool for generating space-dependent models simplifies the setup of turbulent reacting flow simulations by automatically coupling turbulence, chemical species transport, and heat transfer.

Dr. S. S. Prabhu, Tata Institute of Fundamental Research
In this keynote talk, Dr. S. S. Prabhu, a professor from the Tata Institute of Fundamental Research (TIFR), will illustrate how the COMSOL Multiphysics® software is being used for designing and optimizing metamaterials, photonic crystals, and terahertz (THz) sources and detectors. Dr. Prabhu's team has developed several terahertz optical components like lenses, mirrors, and setups using the Ray Optics Module and Wave Optics Module add-on products in COMSOL Multiphysics®. They have simulated a photoconductive antenna (PCA) emitting terahertz radiation with high average power using optimized plasmonic electrode geometries and photonic crystals. One such example is a device consisting of Au electrodes on a semi-insulating GaAs substrate.
Dr. Prabhu will also discuss a photonic crystal, such as a plasmonic nanostructure array embedded in a substrate between two electrodes. This array shows plasmonic enhancement of the 800 nm infrared radiation (IR) light near the nanostructures enhancing THz radiation emission. He will discuss the field enhancement seen in the COMSOL simulation and its comparison with experimental observations. Dr. Prabhu will also cover how metamaterial designs have been simulated with the help of an array of different elements such as rectangular slits, split ring resonators, rods, and rectangular trenches. He will talk about the resonant transmission of the light seen for these various types of designs and the evaluation of these results against those obtained experimentally. Finally, Dr. Prabhu will touch upon the LiveLink™ for MATLAB® Module and how this has been used with machine learning and artificial intelligence algorithms to design a metamaterial.
COMSOL Multiphysics® version 6.3 introduces a range of new features for fluid flow and heat transfer modeling. Reynolds-stress turbulence models enable accurate simulations of secondary flows in ducts and flows with strong swirl or mean rotation, and a new kinetic energy option enhances simulations of high Mach number flows. Shear-induced migration in multiphase flow modeling supports applications such as particle fractionation and microfiltration. The new mixing plane functionality simplifies the modeling of pumps, turbines, and other rotating machinery. Additionally, the release introduces tools for simulating non-Newtonian flow in porous media.
Heat transfer modeling is extended with a repeating unit cell method for composites and porous media, alongside a forward ray-shooting technique for improved accuracy in external radiation. Performance improvements include faster surface-to-surface radiation simulations for large models and enhanced workflows for fast drying simulations using nonequilibrium moisture transport.

Ashutosh Pailwan, Adani Electricity
The power distribution sector increasingly relies on advanced modeling tools such as COMSOL Multiphysics® to ensure reliability, efficiency, and safety. COMSOL® enables engineers to assess the electromagnetic impact of components such as power lines, transformers, and substations, addressing challenges like electromagnetic interference (EMI) and ensuring compliance with electromagnetic compatibility (EMC) standards. Some of the key applications include EMI mitigation through electromagnetic field analysis, thermal-EM analysis to estimate Joule heating in cables and busbars, and electric field distribution studies for preventing insulation breakdown. COMSOL® also supports health and safety assessments with its functionality for simulating electromagnetic exposure levels, which can be used to ensure conformance with standards required in regulations. In this talk, Mr. Ashutosh Pailwan from Adani Electricity will discuss how COMSOL® offers holistic insights through its capabilities for coupling electromagnetic analysis with mechanical, thermal, and acoustic domains, which helps in the optimization of designs, reliability enhancement, and compliance with regulations within the power sector.
COMSOL Multiphysics® version 6.3 introduces new capabilities and performance improvements for structural mechanics and acoustics simulations.

New interior boundary contact conditions eliminate the need for contact pairs, and viscoelastic time-domain simulations incorporate frequency-dependent material properties. Additional updates include geometry modeling for random particulate composites, a lattice geometry part library, and up to 50% faster plasticity computations, with added support for pressure-dependent plasticity in foams.
For acoustics, GPU acceleration enables time-explicit pressure acoustics simulations that are up to 25x faster. Time-domain modeling now supports frequency-dependent material properties, and the sequential linearized Navier–Stokes (SLNS) model provides faster thermoviscous acoustics computations. Updates also include tools for anisotropic poroacoustics modeling.
