Welcome!

This site www.grid-cfd.ru is intended to exchange ideas on a development of effective grid generation for solution of CFD problems.

OrthoGrid – is a grid generator which was developed 15 years ago for automatic generation of an orthogonal grid on a plane. For theoretical aspects of this generator go to here ».
It is based on a simple control of spacing resolution – through a step on the curvilinear coordinate. The ratio of Lame’s coefficients is accepted to constant for the whole solution domain. A grid constructed by means of orthogonal grid generator, is the most suitable for problems of hydrodynamics because its curvilinear coordinates are streamlines and isobars of potential flow.

HexaGrid – is a traditional multiblock generator with structured hexahedral cells. It has all necessary toolkit for grid generation in three-dimensional domain. To see how it works go to here ».
Transfinite interpolation is used for grid generation.

The further improvement of grid generation method is seen in two directions:

1. Development of most friendly interface, when a goal is achieved by minimal number of necessary commands/operations.

2. Automation of process of generation. For the block-structured generator this means that the edges are created manually, and further process of formation of cells is carried out automatically.

For additional information, as well as place your material on the site can be in touch with me through the section Contacts ».
