    #106 - Podcast - Tim Rawling | CalcTree in 2026

    This episode’s guest is Tim Rawling, a Founder at CalcTree, a calculation management platform now about four years old. He was on the podcast a couple of years ago, not long after he started there, when the product was positioned as calculation tool that had interesting collaboration and management capabilities. Here we are, two years later and he’s covered a lot of ground since then. Tim is based in Australia and spends a lot of time talking to global engineering firms about the same set of problems. He is also still on the tools, pushing code and testing workflows, which makes this a worthwhile conversation. We are working on adjacent problems from different directions, and it’s fascinating to explore how we are all riding these waves of innovation and change together. CalcTree sits somewhere between Notion and Mathcad. Pages are markdown, calculations run on MathJS with native unit arithmetic, and there is a Python engine behind the page for anything the calculation library does not cover. Multiple people can work the same page live. The AI layer builds calculations, reviews them, and reads from a vectorized workspace knowledge base so it produces work in the context of your own standards and checklists. Before the call I sent Tim two unlabeled datasets and a Python script with no context. In the episode he turns that into a run-of-river hydro report on the platform, pretty cool. Other ground covered: * Adopting a tool like this and making decisions with so many options * Model selection inside the platform, and how effort and thinking settings trade against a monthly token allowance * The billable hours problem. If the work takes less time, what happens to the fee. * Linked references, so a reviewer can click a code clause in a calculation and land on the actual table with its surrounding context rather than a screenshot * The dependency graph view, and what it’s for * Quality assurance and control. I recommend subscribers take a look for themselves, CalcTree is a powerful platform and full of useful features for team-based engineering work. There is a generous free tier with access to the built-in template library, which contains around a hundred calculations across Australian, US and European codes. Tim like the GLM models, GLM 5.3 has recently released and I think it’s a great model too. Worth checking out on Fireworks. Great to speak with Tim, as always.

Peter has worked extensively with Arup as part of their Oasys software team, contributing to some of the most advanced solutions for finite element analysis (FEA), structural design, and crowd simulation. Peter is also the author of one of my favorite engineering books, ‘Computational engineering’. It’s the first engineering book that I’ve read in a long time that made me smile. Full of practical advice and ‘engineeringisms’ that help you think more clearly. I read it on my phone during my daily commute over a few weeks. Loved it. IStructE Online Store | Peter Debney - Computational engineering Topics Covered in ‘Computational engineering’: * Design (including parametric design) * Modelling (and its problems) * Analysis (basics and methods/linear, nonlinear, and dynamic) * Optimization * AI and machine learning * The future of engineering software I highly recommend Peter’s book to all structural engineers. It’s full of invaluable advice and insights on how to think critically about engineering and approach problems in the most practical way, and not just in relation to computational design. I wish there were more books like it. We dive into some of these topics today, but we'll also be discussing Peter's career journey, how he transitioned from traditional structural engineering to becoming a domain expert in computational design, and his involvement with the Institution of Structural Engineers (IStructE), where he’s currently the Chair of the Yorkshire Regional Group and a member of the Digital Workflows and Computational Design Panel. We talk about the increasing role of automation, machine learning, and AI in engineering workflows, and how computational tools are shaping the future of the industry. Peter shares his insights on avoiding common pitfalls in FEA models and the benefits of understanding structural behavior before relying on software. We explore the mindset required for modern engineers to succeed in a world that increasingly relies on computational approaches. Peter offers great advice for young engineers on how to approach computational design, mastering problem-solving techniques, and even how learning a musical instrument can improve your understanding of dynamics in structural engineering. Links to items discussed: * Sydney Opera House 50 years on (A great read) * Confessions of a Computational Engineer (Peter’s talk for IStructE on his career path) * https://www.oasys-software.com/ (Oasys Structural Software) I also want to acknowledge Peter's inspiring journey. He has overcome significant personal challenges, including dyslexia and speech barriers, and has become a powerful advocate for progression and adaptive approaches to neurodiversity in our profession. Another great discussion with a fascinating character. These podcasts are a lot of fun and I appreciate the kind words from everybody, wherever you are on the planet. I loved Peter’s book. It reminded me of the great ‘Structures: Or Why Things Don't Fall Down’ by JE Gordon. Another great read and one that Peter noted as an inspiration. I always welcome recommendations for new books, please comment below with your suggestions. See you in the next one!

    In today’s episode, I welcome Ramaseshan Kannan, the Head of Computational Science at Arup and a Royal Academy of Engineering Industrial Fellow. With a PhD in Numerical Linear Algebra from the University of Manchester and a career that spans both industry and academia, Ramaseshan is at the forefront of research in our industry as it relates to computational science, machine learning, and numerical analysis. * Connect with Ramaseshan Kannan | LinkedIn At Arup, Ramaseshan drives the development of advanced algorithms and finite element solvers, bringing innovation to the built environment. His work is a powerful blend of theory and practice, pushing the boundaries in high-performance computing, uncertainty quantification, and optimization. This area of research is one of deep personal interest to me. While Ramaseshan delves into the underlying theory and mechanics, myself and many others are on the other side of the fence, trying to implement the types tools and ideas that he creates into practical applications for our clients and projects. It’s an exciting time to be in engineering, as more tools are becoming available that are increasingly approachable, though each comes with its own learning and opportunity costs. The decisions we make about which tools to invest our time in are crucial—and often, it’s only in hindsight that we understand their true value. But such is the art of progress, it’s only after the fact we realize we were banging our head against the wall. My conversation with Ramaseshan was both inspiring and thought-provoking. I had a fantastic discussion with him, and I look forward to our next conversation. He’s a remarkable thinker, and I’m eager to see where his ideas and his work will lead. Thank you for being part of the Flocode community. It’s been a lot of fun so far. I will have more announcements soon. See you in the next one. James 🌊 Notes: * What Could Possibly Go Wrong? Meta Tools for Digital Tools and Workflows 🛠️ - By Ramaseshan Kannan * CSIC Research Talk by Dr Ramaseshan Kannan “Blending data-and computational sciences for sustainability” * Royal Academy of Engineering Ramaseshan spoke briefly about the potential of LLM’s in the geometry or parametrization space and since our conversation, I found the following: World Labs, a newly formed company, said Friday (Sept. 13) that it has raised $230 million to build large world models (LWMs) that “perceive, generate and interact with the 3D world.” “We aim to lift AI models from the 2D plane of pixels to full 3D worlds — both virtual and real — endowing them with spatial intelligence as rich as our own,” the company said in a Friday post on LinkedIn.
