FlowPhys AS specializes in developing tailormade scientific software that requires advanced numerical methods and physical models, as well as also performing computer simulations.

Flowphys software capabilities

Our main product is the software FlowPhys, a finite element multi-physics simulation software for general geometries in 1D, 2D, and 3D geometries. Some of the features of the FlowPhys software are:
• 1D, 2D, 3D heat transfer, fluid dynamics (CFD), structural dynamics, electrostatics, acoustics
• 1D circuits (multi-phase pipe flow, electric circuits)
• Linear and non-linear, steady state & transient
• System-based Modeling, process simulation, process control algorithms
• Multi-phase, multi-component, incompressible & compressible flows with Newtonian & non-Newtonian fluids
• Computational chemistry equilibrium & reaction kinetics, corrosion, erosion, scaling
• Coupled analyses
• Shape, parameter, and process optimization
• Data-driven (AI/ML) models, AI enhanced physics models, physics informed AI models

Tailor made simulator plugins

We are not only specialized in making our own stand-alone simulation software, but also dedicated in developing tailormade physics and data-driven simulators that can be used as plugins to other software as well as websites.

The Flowphys3D software is used for multiphysics simulations in many different areas and applications. The simulations contribute to improve understanding and de-risk the development process. Click to see more.

The Flowphys1D software is used for circuit analyses of thermodynamic fluid flow and electric circuits. Many different device models exists, and we are also able to develop and implement new tailormade models. In addition to engineering design & analyses, the software is also suitable for system-based modelling, process controls, tailormade Virtual/Digital Twins. Click to see more.

FlowPhys has developed a new and unique geothermal flow assurance simulation software for engineering and scientific analyses. To improve and optimize planning, design, and operation of geothermal energy systems and facilities, it is necessary to have a good understanding of the operating conditions in the different parts/locations and their time dependancies. The Flowphys Geothermal Flow Assurance Simulator combines fluid dynamics, thermodynamcs, and geochemistry to provide detailed analyses and simulations. The area of Flow Assurance originated in the Oil & Gas sector, where it has grown to become a key enabling technology, leading to significant cost reductions. Click to see more.

To improve the value and impact, we frequently perform shape and/or process parameter optimization, often with spectacular results. Click to see more.

We use data-driven AI/ML/statistical models both to provide AI-enhanced physics models as well as physics-informed AI models. The AI models are particularly suitable for Online Simulators, as they provide much faster simulations. Click to see more.
