Spann.AI

Spann Engineering Consulting LLC uses the simulation capabilities in the COMSOL Multiphysics^® software to help R&D teams make physics-informed design decisions before prototyping. The firm serves clients in clean energy, medical devices, pharmaceuticals, and nanotechnology. Founder Andrew Spann brings a decade of multiphysics consulting experience across these industries, including projects that have resulted in patents and peer-reviewed publications.

Spann Engineering Consulting LLC is committed to helping its clients find a solution to their engineering problems, based on transparent assumptions and careful verification. Spann.AI’s deliverables have an additional focus on lasting capability: Models are organized and documented so the client's own engineers can perform further studies with AI coding agents to conduct subsequent parameter sweeps, design variants, and generate plots. AI-assisted capabilities are applied only where they meaningfully accelerate the work without adding verification burden. The goal is always the engineering problem, not AI adoption for its own sake.

Consultant Contributions

At his previous consulting company, founder Andrew Spann partnered with COMSOL to lead a webinar for the American Institute of Chemical Engineers (AIChE). The webinar showed how engineers can optimize the performance of a medical screening device and use the Java programming features in COMSOL Multiphysics^® to accelerate the rate of development. The webinar can be found here.

His contributions to the COMSOL Conference include eight co-authored papers:

1. 3D Printed Microfluidic Medical Devices: Rapid Prototyping Using LiveLink™ for MATLAB^®
2. Mixing Considerations in Chemical Reactor Scale-Up
3. Chemical Gradients, Carryover and Mixing in Fluidic Diagnostic Systems
4. Blood Damage Modeling of FDA Benchmark Nozzle
5. Chemical Mixing and Washing in Fluidic Diagnostic Systems
6. Eddy current thermography feasibility study using COMSOL Multiphysics^®
7. Multiphysics Simulation of Chaotic Mixing in Microfluidic Devices
8. Deep Neural Network Surrogate Model for Blood Damage Modeling in FDA Hemolysis Benchmark

In addition, Spann will explore how AI agents can be used to solve problems in COMSOL Multiphysics^® in an upcoming post for the COMSOL Blog.
