Physics Simulation Made Easy

Banner - Physics Simulation Made Easy

Precise Simulation Ltd. was established after two decades of developing both commercial and academic Finite Element Analysis (FEA) and Computer Aided Engineering (CAE) simulation software and noticing a real disconnect between simulation software, developers, and its users. That is, the frustration of having to choose between very complex and expensive closed source commercial software tools, or state-of-the-art but often even more difficult to use (and even to get to compile and run) academic and open source codes, with virtually nothing in between.

Precise Simulation - Developer of Easy to Use Physics Simulation Software


The fundamental idea and long term goal of Precise Simulation is to develop and be able to provide truly easy engineering and physics simulation software that everyone should be able to use right away. The ultimate vision is that software should be so intuitive that users do not require any documentation at all, at least not for learning how to set up and perform basic tasks.

FEATool Multiphysics

FEATool Multiphysics is a physics and partial differential equation (PDE) simulation toolkit which combines a very easy to use graphical user interface (GUI). At the same time FEATool allows power-users to fully integrate physics simulations in to their own workflow, by being fully scriptable and extensible with the MATLAB and Python languages and toolboxes.

In addition, FEATool fully integrates state-of-the-art open source solvers such as FEniCS, OpenFOAM, and SU2, external mesh generators Gmsh, Netgen, and Triangle, and the postprocessing and visualization tools ParaView and plotly. This enables anyone to use these solvers and simulation tools without much effort, which otherwise would take a significant time to understand and learn how to use.

CFDTool is a toolbox specifically designed to make fluid mechanics and heat transfer simulations easy to get started with. Based on the FEATool Multiphysics code base, CFDTool features a simplified GUI which enables users to get started with flow simulation right away, and not requiring understanding complex systems of partial differential equations (PDE).

CFDTool - MATLAB Computational Fluid Dynamics (CFD) Toolbox

CFDTool is aimed at beginners when learning CFD simulations, while FEATool Multiphysics offers more features for advanced and power users who want to customize their simulations in some way (for example with scripting and modifying PDE equations). When moving from CFDTool to FEATool, models can be seamlessly loaded into FEATool and extended with more multiphysics functionality.
