DiodoreHydrodynamics and motions analysis of floating systems
Marine EngineeringSoftware Datasheet
Diodore is a general purpose hydrodynamics
program combined with a mechanical solver for the
motions analysis of naval and offshore floating
systems.
Diodore offers a wide range of applications in
offshore engineering, harbor engineering and naval
architecture.
Hydrodynamics features include advanced
hydrostatics analysis, radiation/diffraction solver
with forward speed capable of handling multi-
bodies interactions, full QTF formulation for low
frequency diffraction analysis and wave resistance
models. The mechanical solver includes frequency
domain and non-linear time-domain dynamic
simulation features for the assessment of the globalperformance of floating systems.
Diodore forms part of the marine software solutions
developed by Principia.
Applications
