Advanced thermodynamics software

To increase operational efficiency, Multiflash^® , a comprehensive PVT (Pressure, Volume, and Temperature) modeling and physical properties software, empowers engineers to predict the phase behavior and transport properties of complex fluids in oil and gas, refining, petrochemical & polymer, energy, and process industries.

Thermodynamics and Physical Properties for Net Zero

Fluid modeling is carried out at various stages in design and operations. However, the lack of appropriate models and consistency across disciplines often causes delays, uncertainties, and costly mistakes. While this situation leads to excessive CAPEX/OPEX, it may also cause health and safety hazards and catastrophic damages to facilities.

Multiflash supports your organisation along its digital transformation and transition journey toward net zero by:

Accurately predicting phase behavior increasing operational efficiency.

Seamlessly integrating with other modeling tools providing effective collaboration.

When a driver crosses a soaring cable-stayed bridge or a train rumbles over a weathered steel truss, they rarely consider the silent pact of physics beneath them. They are riding on the superstructure—the load-bearing crown of the bridge. While the substructure (piers, abutments, and foundations) fights the forces of earth and water, the superstructure must master the sky. It is here, in the design of girders, trusses, arches, and cables, that engineering meets existential risk. bridge engineering handbook superstructure design

Parametric design tools (using Grasshopper or Python) allow engineers to optimize girder depth continuously along the span. Instead of a prismatic beam, a modern superstructure is a variable-depth sculpture —thick at the piers for negative moment, thin at mid-span for economy. The handbook provides the parametric equations to generate these shapes, reducing steel tonnage by 15-20% compared to uniform designs. The Bridge Engineering Handbook does not treat superstructure design as a checklist. It treats it as a contract between the present engineer and the future public. Every camber calculation, every weld detail, every drainage slope is a promise that a child crossing the bridge in 2090 will be as safe as one crossing it today.

It’s not about collapsing; it’s about annoying . Excessive deflection under a loaded truck cracks the deck waterproofing. Unchecked vibrations at pedestrian pacing frequencies (1.5–2.5 Hz) cause mass panic. The handbook includes updated formulas for pedestrian-induced lateral forces —a lesson learned from the 2000 London Millennium Bridge wobble. It is here, in the design of girders,

Real Fluids

Anticipate the phase behavior and transport properties of highly non-ideal fluids across the chemical, petrochemical, and oil and gas industry, from the reservoir to refinery.

Flow Assurance

Accurately forecast the risks associated with the formation of pure solids, hydrates, wax, and asphaltenes while assessing mitigation or remediation strategies.

Embedded Applications

Integrate the threadsafe Multiflash PVT engine in workflow, software, or hardware solutions through the standard Cape-OPEN interface, native EXCEL® plugin, or standard APIs.

Asset Integrity

Predict the partitioning and phase behavior of hazardous substances to help asset integrity engineers and production chemists manage the risks to facilities.

Reservoir PVT Modeling

Characterize petroleum fluids through compositional or black oil data, and tune equations of state and physical properties models through PVT experiments.

Our expert on Multiflash

"Over the 30+ years of its development and market presence, Multiflash has established itself as one of the standards in PVT modeling across the process industry. The specialization and accuracy of predictions in applications such as flow assurance or process modeling have traditionally driven the evolution of the software. More recently, energy transition and digitalization have started to cause a shift in the focus of oil & gas, and process industries. Multiflash is at the forefront of this transition, with new applications and models, as well as innovative and more performative ways to access its capabilities across disciplines and platforms, to provide engineers with a truly unique solution for their needs of accurate predictions of phase behavior and physical properties."
