S7E21 Rod Scholl | Pro Tips from 30-Year Analyst For Accurate Simulations (FEA & CFD)

Being an Engineer · 15 May 2026 · 48m · Episode 21

What this episode covers

Rod Scholl, founder of Epsilon FEA, discusses the critical role of engineering judgment in Finite Element Analysis (FEA) and Computational Fluid Dynamics (CFD), contrasting his early career at Honeywell and PADT with his current consulting work. He explains that simulation is most valuable when used as a calculator for specific decisions rather than for open-ended information gathering, emphasizing the importance of knowing what action will be taken based on the results. Scholl shares anecdotes about navigating complex technical challenges, such as a difficult evaporation simulation, and highlights the dangers of 'unknown unknowns' where engineers lack the ancillary knowledge required for accurate fatigue or stress analysis. He advises companies to bring in external expertise to transfer knowledge and avoid the pitfalls of siloed internal teams.

    How Simulation Technology is Reshaping Product Design w/ Dr. Masha Petrova

    Dr. Masha Petrova, CEO of Nullpace, explains how engineering simulation (CAE) allows manufacturers to design thousands of variations digitally before manufacturing only a few, replacing costly physical prototyping. She discusses the industry's shift from a few legacy providers like ANSYS and MSC Software to a consolidation trend driven by AI and chip industry demands, noting that venture capital has historically overlooked this rigorous field. Petrova highlights the challenge of tool adoption, where engineers lack time to evaluate new software, and proposes that companies must incentivize this exploration to keep pace with innovation.

    Industrial design prototyping vs simulations - IDology #21

    Piotr Dalewski and Mikołaj Wiewióra of Mindsailors discuss the strategic balance between physical prototyping and computer simulations in industrial design. They explain that while prototypes validate ergonomics, assembly, and tactile feedback, simulations like Finite Element Analysis (FEA) and ray tracing optimize mechanical stress and optical properties before tooling. The guests emphasize that both are necessary investments to mitigate risk, with the choice depending on project scale, cost, and the specific physical phenomena being tested.

    S3 E1: Mastering Tech Adoption and The Hardware Development Workflow with Jon Hirshtick

    Jon Hirshtick, founder of SolidWorks and Onshape, discusses the evolution of hardware development tools, emphasizing that software is a tool rather than a solution. He explains how customer visits and inferring needs drove the creation of features like the feature manager and cloud-native workflows. Hirshtick advises software founders to focus on usage metrics, understand market size realistically, and avoid the gap between demo and real-world complexity. He also shares lessons from his time on the MIT blackjack team regarding failure, persistence, and team dynamics.

    Simulation as an Enabler: Pan Michaleris & Erik Denlinger on the Evolution of Additive FEA

    Pan Michaleris, founder of Pan Optimization, and Erik Denlinger, co-founder and chief engineer, discuss the evolution of finite element analysis (FEA) in additive manufacturing. They explain how PanX software predicts distortion, thermal stress, and material properties to replace costly trial-and-error builds, particularly for large aerospace components. The conversation covers the shift from expert-driven simulation to automated workflow integration with machines like EOS and Velosis, and the cautious role of AI surrogate models in qualification.

    An Interview with Steve Kreuzer

    Steve Kreuzer, a mechanical engineer and PhD from UT Austin, explains his transition from academic biomechanics to consulting at Exponent, where he analyzes failures in physical products. He details how Exponent uses finite element analysis (FEA) and computational fluid dynamics (CFD) to investigate issues like battery thermal runaway and BGA solder joint failures in electronics. Kreuzer discusses the specific mechanical risks of lithium-ion cells, the importance of protecting cells from environmental stress and containing thermal events, and how simulation guides design fixes like stiffeners and spacing.
