Simulation Examples

• Other examples

Analysis Field

Fire Analyses

Get insight into the spread behavior of smoke and temperature variations due to fires in plants, warehouses, and other buildings to use in examining problems and improvements to fire prevention and detection systems.

Water flow Analyses

Water flow analyses not only simulate gas and liquids but also solids and liquids imitating carriers and other catalysts supports as well as vibrations to evaluate liquid surface and other behavior.
These analyses are effectively used for applications such as aeration stirring basin, MBR treatment, and other simulations for water treatment facilities, river and other water level simulations during floods, flow velocity behavior in pipes, cavitation prevention measures, and other equipment simulations, and evaluations of the efficiency of water heat storage tanks and other building simulations.

Structural Analyses

Structural analyses obtain deformation, stress, and strain results for torque, velocity, stress, displacement, heat, and a variety of other loads.
These analyses can even verify the limit strength by taking into account various nonlinear behavior. These results help in not only reviewing designs but also in identifying and creating measures to prevent the cause of accidents.

Fluid Dynamics Analyses

Fluid dynamics analyses can simulate a board range of phenomenon, such as plant pipe flow, pumps, turbines and other fluid machinery, HVAC and cooling water systems, and overflow caused by agitating liquid surfaces. These results can support fluid-related development, greater efficiency, a better environment, and measures to prevent troublesome issues. These simulations visualize the invisible.

Thermal Analyses

Thermal analyses simulate the heat distribution from the transfer of heat. These simulations can obtain deformation, stress, and strain results for temperature fields.
Engineers can grasp the heat distribution of products and verify heating and cooling conditions.

Special Analyses

These specific simulations perform fire, magnetic field, machinery, optimization, and coupled analyses.

Collision Analyses

Collision analyses simulate dynamic behavior with short yet strong nonlinear properties, such as falling structures and other types of collisions.
For example, these simulations can determine the potential outcome of a structure in a fall or collision by taking into account the plasticity, failure, and strain rate dependency of the material.

Vibration Analyses

Vibration analyses can obtain the eigenvalues of structures or the response to dynamic loads.
For example, engineers can run a vibration analysis that takes into account resonant frequency of earthquake loads and other vibrations to investigate potential outcomes. These analyses can even take into account various nonlinear behavior.

Evaluations Based on Standards and Requirements

Engineers can process the analysis results and confirm whether a work product satisfies standards or requirements by running an analysis that applies those standards or requirements, such as primary stress, primary plus secondary stress, and even fatigue evaluations.

Main Analysis Support Services

Product Development Support

We support preliminary assessments in the product design stage through analyses.
This helps with product evaluations and provides advantages such as shorter development timelines.

Resource Support

We support customers who lack the necessary resources, such as insignificant staff to run analyses or a lack of software licenses to run many simulations with many different parameter settings.

Troubleshooting Support

We support the troubleshooting essential to discover causes and create countermeasures through analyses.

Support for Adopting and Using CAE

We help customers who want to start using CAE by providing assistance and education on adoption and use so that everyone can take full advantage of CAE.

Support in Cooperation with the Hitachi Group

Cooperation with the Hitachi Research Institute and other Hitachi Group companies connects customers with Hitachi Group technologies in an effort to help them overcome their challenges.

Support Creating Analysis Models

These services assist customers in creating large-scale and complex models.

Hitachi Plant Construction uses ANSYS Fluent and various other CAE software to provide these analysis support services.
