Computation of the ship hull flow with help of complexes of hydrodynamical analysis now gets the increasing practical value in the domestic and foreign organizations. Definition of the stream flowing near the hull of a vessel, at early stages of its designing allows solving qualitatively tasks of optimization of the hull form and configuration of the appendages; studying of operating conditions of thrusters, steering devices and bow thrusters; definition of trim of high-speed crafts; definition of engine plant power of the vessel. However it is clear that all aforementioned advantages of the computational fluid dynamics methods can be fully implemented only under condition of a good coordination of received results with the most reliable experimental and theoretical data.
The report is devoted to a series of calculations of perspective containership towing resistance, executed in a program complex "FlowVision".

The constant grow of the motor fuel prices increases the recuirements to the quality of ship propulsion study on the design stage. Some unusual approaches that applies during development of the "Volgo-Donmax" class shop project (MEB project name RSD19) are described in this article.

An approach for solving Fluid Structure Interaction in aerospace application is presented in this article. The proposed approach is based on the two-way coupling between CFD code FlowVision and FEA code ABAQUS. The codes are coupled directly without using any 3rd party software or intermediate structure. A direct link offers a full control over the load transfer and interpolation error free data exchange between the codes. The direct link is implemented using special meshing techniques (submerged meshes in FlowVision). FE mesh is subtracted from the Cartesian CFD mesh; all links between CFD mesh cell and outside faces of the finite elements are preserved. Node displacements are transferred directly between FlowVision and Abaqus without any interpolations.

An advanced finite-volume method (method of modified finite volumes) for numerical simulation of flows in industrial applications and its implementation in code FlowVision is proposed. The method is based on non-staggered Cartesian grid with adaptive local refinement and a subgrid geometry resolution method for description of curvilinear complex boundaries. Semi-Lagrange approach for solution of convective transport equation and splitting algorithm for solution of Navier-Stokes equations are presented.
Opportunity of solution of real industrial problems by the method of modified finite volumes is estimated. Geometry of computational domain is specified by CAD system and is imported by FlowVision through VRML or STL file.

Numerical simulation of water flow around rotated car tire is one of the challenging problems for computational fluid dynamics (CFD).

Main difficulties of the problem are :
- the presence of three phases - liquid, gas, rigid body - in computation domain;
- the tire motion relatively the computation domain;
- complex tire shape and large ratio between scales of tire diameter (500-1000 mm) and tread channels (2-10 mm);
- variation of tread surface under loading;
- motion of free water surface with possible water wave breaking down.

The adequate numerical method allowing to overcome all these difficulties is need to solve the problem. The main question is the choice of a grid type. The commonly used grids may be classified under non-structured grids (NSG), structured curvilinear grids (SCG) and Cartesian structured locally refined grids.
