Green Energy
By their very nature, green energy generating structures come under eco-friendly scrutiny, with the need to build economically, safely and with an eye service life. DIANA can help you skilfully achieve these goals.
Moving from fossil to green energy
Advancing environmentally friendly design
The focus of the world has changed from fossil fuel energy to green and sustainable energy. The target is now in identifying new energy resources, among them hydropower, wind, solar and geothermal energy. The sharp edge of technology is essential to making this achievable.
Utilization of software products such as DIANA becomes more clear-cut in order to optimize design of reference structures, eg. Foundations or shafts, or dam bodies to facilitate and adapt to these new green energy requirements in everyday life.
Advance with analyzing renewable power plants
Essential for wind, solar and hydro based structures
Mechanical structures such as wind turbines or hydroelectric plants are complex. Interaction between mechanical and structural parts of these renewable power plants, and every day impact factors such as water, wind, heat and/or vibration.
This type of investigation requires a powerful, and thorough analysis tool to comply and simulate all the above interactions. DIANA is equipped with a range of analysis types to allow the user to understand how the structures will react to everyday forces by performing soil-structure, fluid-structure, temperature and dynamic analyses.
