Simulation of the deformations, vibrations, stresses and strains of general three dimensional structures by means of finite element analyses (FEA). Linear and non-linear analyses (plasticity, contact problems) are possible. Several interfaces to CAD data are available.

The experience of DELTA JS covers structures such as

• casings,
• foundations,
• turbine blades,
• compressor and expander impellers.
