Green Energy

By their very nature, green energy structures are scrutinized for eco-friendliness, economic efficiency, safety, and service life. DIANA can help you skillfully achieve these goals.

From fossil fuels to green energy,
advancing environmentally friendly design 

The focus of the world has shifted from fossil fuel energy to green and sustainable energy, targeting new resources such as hydropower, wind, solar, and geothermal energy. Cutting-edge technology is essential to make this transition achievable. The utilization of software products like DIANA becomes crucial to optimize the design of reference structures—such as foundations, shafts, and dam bodies—to facilitate and adapt to these new green energy requirements in everyday life.

Essential for wind, solar, and hydro-based structures

Mechanical structures such as wind turbines or hydroelectric plants are complex, involving interactions between mechanical and structural components. These renewable power plants are subjected to everyday 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.
