LVMFlow - professional solution for developers of foundry technology. Modern foundry technology now allow production of high quality castings very complex configuration, require virtually no additional treatment. However, the cost of their production remain high. The use of high technology, in particular, of computer modeling of physical and chemical processes occurring during the formation of the casting allows, on the one hand, the transition to the casting more and more complex forms, using an increasing range of alloys, on the other hand, to reduce the cost of debugging technology, replacing the natural experiment computing. Modern computer simulation program based on the physical theory of heat, diffusion, hydrodynamic, and deformation phenomena can adequately reflect the pattern of physical and chemical processes occurring in the liquid metal filling in the form, the crystallization of a multicomponent alloy, annealing, etc.
