Marine Specific Solvers


OPTNAV is a multipurpose optimization tool for hull design. It combines different solvers such as Hydrostatics, Holtrop Resistance, Intact Stability Check, with a powerful modelling and deformation engine. These different features are orchestrated to generate precise design of experiments (DOEs) with automatic mesh generation of modified hulls, and pre-evaluation of hulls performances.


REVA is designed to solve the problem of ship resistance in calm water. It performs computations on monohulls, catamarans and trimarans taking into consideration lifting surfaces. It allows to model the influence of the floor and walls of towing tanks and air cushion effects on the free surface.


ISIS-CFD uses unsteady, incompressible Reynolds-Averaged Navier-Stokes equations (RANS). It implements the finite volume method to build a spatial discretization of the transport equations. The face-based method is generalized to two-dimensional, rotationally-symmetric, or three-dimensional unstructured meshes for which non-overlapping control volumes are bounded by an arbitrary number of constitutive faces.
