Engineering & Simulation Consultants

EXPLICIT DYNAMICS ANALYSIS

We provide explicit dynamics analysis to characterise the physics of short-duration events for products that undergo highly nonlinear, transient dynamic forces. Our analysis gains insight into how a structure responds when subjected to severe loadings from another solid object. 


Short-duration severe loading analysis to study the interaction between various solid bodies


Low velocity object crashing into a structure such as:

- Hostile vehicle mitigation such as a truck or a ute crashing into gate barriers or bollards

- Crash test of a large ships
- Bird-striking an aeroplane wing


High velocity object penetrating a structure such as:
- Penetration mechanics of ballistic impacting into a composite material

- Material resilience study from blast fragment breaches

BLAST EFFECTS ANALYSIS

Our blast effects analysis (BEA) consultants use ANSYS Autodyn to simulate the response of materials to short duration severe loadings from impact, high pressure or explosions. We simulate complex physical phenomena such as the interaction of liquids, solids and gases; the phase transitions of materials; and the propagation of blast waves. Our BEA consulting services include:


- Aerospace Applications: aircraft impact, space shield design and space debris impact

- Chemical & Petrochemical: gas pipe explosion, vessels explosion and vapour cloud explosions

- Critical Infrastructure: structural response and effectiveness of mitigation measures

- Explosives Development: studying the brisance of high explosives

- Land Applications: armour, anti-armour, mine protection and vulnerability against IEDs

- Material Science: properties, effectiveness of ballistic glass and reinforced concrete
- Naval Applications: vessel vulnerability and underwater blast

- Personnel Protection: body armour, helmet against blast effect and projectiles

- Public Space: predict casualty rate at public transport eg airport, train station, bus interchange

FLUID STRUCTURE INTERACTION

The flow of fluids through pipe connections, over aerofoils, turbine blades and other structures can generate unsteady forces on the surrounding parts that cause them to move. This movement may be intentional and necessary or unintentional but unavoidable. Our simulation consultants which consist of FEA and CFD consultants are experience in coupling various modelling & simulation tools allow us to perform fluid structure interaction (FSI) analysis which can assist the clients to understand and solve product design challenges. Our FSI & simulation services include but not limited to:

Fluid Structure Coupling
- CFD based applications
- Mechanical based applications

Thermal Structure Coupling
- Engines, gas turbines, heat exchangers
- Cryogenic components and systems

COMPUTATIONAL FLUID DYNAMICS

Our simulation consultants use ANSYS Fluent which is the most-powerful CFD simulation software tool available, empowering our clients to go further and faster as we optimise their system's performance. Fluent includes well-validated physical modelling capabilities to deliver fast, accurate results across the widest range of multiphysics applications. The simulation analysis projects our CFD consultants undertake are related to aerodynamic studies, single-phase, multiphase phenomena, multispecies, multiphysics, reaction chemistry, sliding mesh, combustion, energy and solidification-melting processes. Our computational fluid dynamics simulation services include but not limited to:

- Built Environment: wind-driven rain, pollutant emission, smoke propagation, thermal comfort

- Chemical & Petrochemical: unit operations, gas dispersion analysis and vapour cloud explosions

- Defence & Security: air, naval, land, weapons development, terrorist CBR attack scenarios

- Food & Beverage: equipment design, preparation processes, storage and distribution

- Renewable Energy: geothermal, wind power, hydro power and waste heat extraction

- Ship Building: design of ship hull, assess propulsion system, gas abatement, ballast water

- Water and wastewater: unit operations, sump pump, stormwater and pressure surge analysis

SIMULATION CONSULTANTS

Our simulation consultants provide simulation services to clients globally across many industries and our simulation analysis employed computational fluid dynamics, fluid structure interaction, explicit dynamics analysis and blast effects analysis.


Currently, we undertake simulation projects from clients based in Australia, Singapore, Indonesia and countries within the Asia Pacific region. We offer the following simulation services: (1) Computational Fluid Dynamics, (2) Fluid Structure Interaction, (3) Explicit Dynamics Analysis and (4) Blast Effects Analysis.


Performing simulation without proper knowledge may lead to misleading results. To ensure the simulation results are accurate, we only assign personnel with a PhD qualification specialised in modelling and simulation. These simulation specialists are supported by conventional engineering to ensure the prescribed solutions are realistic. In addition, we invest in ANSYS simulation software which represent more than 1,000 person-years of R&D and employ only heavily validated models which provide assurance to stakeholders of high accuracy results. Our simulation consultants have a combined experience of over 50 years in modelling & simulation.
