From Scottish Innovation to Global Engineering Solutions
Founded in 2024 in Scotland, PAACS Software Ltd represents the convergence of traditional engineering excellence and cutting-edge computational technology. Our journey from the industrial hub of Glasgow - Scotland, to our new presence in Texas reflects our commitment to serving the global engineering community with world-class simulation tools.
The main ‘thrust’ is to focus on educating attendees on how to best protect highly vulnerable business applications with interactive panel discussions and roundtables.

The software will be free for students to use, additionally it will be free for everyone until stated otherwise.
With the nodal interface and industry standard tools, this is simualtion software great for beginners and experts.
Documentation will recieve regular updates so that anyone can quickly learn the newest features.
Founded in Glasgow, Scotland in 2024, PAACS Software Ltd emerged from a rich tradition of engineering excellence that dates back to the Scottish Enlightenment. Scotland's contributions to engineering—from James Watt's steam engine to modern offshore engineering—inspire our commitment to innovation and precision.
In 2025 we began relocating our operations to Texas, USA. This move centralizes product development, operations, and customer support in Austin while we wind down our UK office. We remain proud of our Scottish roots—and we'll keep collaborating with partners and universities globally—yet our day-to-day operations will now be based in Texas.
Why Texas? Proximity to aerospace, energy, and semiconductor ecosystems; access to talent; and a thriving engineering community. Consolidating in Austin lets us move faster and serve customers more effectively.
Headquarters: Austin, Texas (2025—present)
Founded in Glasgow, Scotland (2024)
Single operations hub in Texas (UK office winding down)
Support for UK/EU customers continues from Texas (extended hours)
Ongoing remote collaborations with universities and partners
Our engineering culture was forged in Scotland; our next phase is built in Texas. This relocation lets us concentrate resources, accelerate delivery, and keep shipping the tools engineers need—worldwide.

“Rooted in Scottish engineering. Built for the future in Texas.”
PAACS leverages world-class open-source technologies and a network of academic research to deliver professional-grade simulation capabilities.
We use OCCT as our geometry kernel for robust CAD operations and advanced geometric modeling. Its evolving feature set and performance improvements help us deliver dependable geometry handling and high-quality mesh preparation.
Our solver layer builds on Kratos Multiphysics (developed at CIMNE/UPC), a modular finite-element framework widely used in research and industry. Its architecture allows us to compose workflows for FEA, CFD, and coupled multiphysics.
For adaptive mesh refinement and optimization, we link the MMG library to achieve reliable remeshing and quality control—helping capture gradients and geometric features that matter for accurate simulation.
For a modern, responsive desktop UI with a native feel, we use Slint’s declarative approach and lightweight runtime to build clear, performant interfaces across platforms.
Kratos Multiphysics is developed by CIMNE/UPC and used by many universities and research groups worldwide. Institutions active in the Kratos ecosystem include:
PAACS is made possible by outstanding open-source projects, including Open CASCADE Technology, Kratos Multiphysics, MMG, and Slint. We are grateful to the maintainers, researchers, and contributors behind these tools.
While PAACS is a proprietary product, we carefully observe upstream licenses and provide clear attribution. Our thanks go to the communities whose work we build upon.
