PhysAI, LLC

PhysAI provides expert multiphysics modeling and app-creation consulting services using the COMSOL Multiphysics^® software, enabling clients to accelerate product development, optimize performance, and ensure regulatory compliance. Founded by a former COMSOL lead developer, all types of physics and modeling levels, from basic apps to the most advanced applications, are readily available.

Areas of Expertise

Applications

PhysAI specializes in the following technical domains, applying them to solve intricate engineering problems:

Application	Description
Computational Fluid Dynamics (CFD)	Modeling microfluidics, laminar, and multiphase flows for biomedical, biofluidics, aerospace, and industrial applications
Electromagnetics	Modeling of all frequencies from DC, through the MHz and GHz part of the spectrum, all the way to THz to design antennas, RF and microwave devices, motors, wireless power transfer systems, and optical systems
Heat Transfer	Analyzing conduction, convection, and radiation in electronics, industrial systems, and biomedical systems
Plasma Physics	Simulating low-temperature plasma, arc discharge, and plasma–surface interactions for semiconductor and plasma-based processing
Acoustics	Studying sound propagation, shockwave propagation, and piezoacoustics for transducers, sonar, room acoustics, and ultrasonic sensors
AI and Surrogate Modeling	Creating surrogate models using deep neural networks and deploying them in real-time embedded systems for model-based control, measurement surrogates, or medical imaging

Thermal Packaging: In acoustophoretic cell sorting, the acoustic field needs to be high enough in amplitude to manipulate the cells, which ultimately leads to thermal dissipation. The maximum temperature shown above is 12 degrees above the temperature of the incoming fluid. Thermal gradients can lead to unwanted effects, including influencing the motion of the cells in the channel.

Industries Served

PhysAI supports all industries, addressing sector-specific challenges with tailored solutions. A small sample of industries includes:

Industry	Applications
Medical Devices	Biomedical systems Implantable devices Diagnostic tools Drug delivery mechanisms
Semiconductor	Electronic components Photonics Plasma processes for chip design and manufacturing
Manufacturing	Manufacturing processes Mechanical systems Fluid–thermal interactions

Building Acoustics: The streamline directions indicate the local energy flux, and the color represents the sound pressure level as ambient noise from the outside enters through a window.

Why Choose PhysAI?

PhysAI was founded by former COMSOL lead developer Daniel Smith, who has over two decades of expertise in high-end finite element analysis, software development, mathematics, and physics. He spent 12 years leading North American development at COMSOL, where he spearheaded the creation of key simulation tools — including the MEMS Module, Plasma Module, Microfluidics Module, Particle Tracing Module, Ray Optics Module, Semiconductor Module, and Molecular Flow Module — which fundamentally reshaped the industry's approach to physics-based computing. This expertise in COMSOL Multiphysics^® allows PhysAI to tackle complex simulations, while their AI-driven approaches, such as surrogate modeling, offer faster and more cost-effective solutions.
