In the world of engineering and science, simulation is one of the most powerful tools we have. It lets us test ideas, validate designs, explore edge cases, and optimize performance — all without building a single prototype. But simulation tools today are often siloed, complex, or expensive. They serve a single domain — like structural mechanics or fluid dynamics — but rarely work together in harmony.
At PAACS Software, we’re changing that.
We believe simulation should be flexible, intuitive, and powerful — something every innovator can use to model the world.
PAACS is being built as a general-purpose simulation tool — one that grows with you. Whether you're starting with Finite Element Analysis (FEA), diving into Computational Fluid Dynamics (CFD), or eventually combining disciplines like electromagnetics, thermodynamics, or controls, we want you to do it all in one cohesive ecosystem.
Our architecture is node-based, letting you connect components like geometry, mesh, physics modules, solvers, and post-processing tools in a clean visual workflow. Each node can be customized, scripted, or replaced — and plugin systems allow whole domains like electrical circuits, controls, or particle systems to be added as needed.
Our long-term goal is to support any kind of physics. This means:
We’re building an engine where these systems don’t just coexist, but actually talk to each other — allowing pressure fields from CFD to drive forces in structural simulations, or thermal simulations to influence material behavior over time.
PAACS is for:
We're committed to keeping it accessible, extensible, and future-ready.
At PAACS, we aim to deliver a reliable, extensible platform that supports simulation across a wide range of physical disciplines. Our architecture is designed to give users control and clarity — whether you're focused on detailed structural mechanics or large-scale multiphysics workflows.
Understanding the complex — through a system that is modular, transparent, and built for real-world engineering challenges.
We’re building a toolkit that enables you to approach any problem with the right combination of methods and modules — and adapt your workflow as your projects grow in scope and sophistication.
Whether your focus is academic research, industrial engineering, or experimental design, PAACS provides the foundation to simulate with precision and flexibility.
