This paper pays attention to the problem of practical applicability of coupled modeling with the use of hard and soft models types and necessity of adapted to that models data base possession. The data base tests results for cylindrical 30 mm diameter casting made of AlSi7Mg alloy were presented. In simulation tests that were applied the Calcosoft system with CAFE (Cellular Automaton Finite Element) module. This module which belongs to "multiphysics" models enables structure prediction of complete casting with division of columnar and equiaxed crystals zones of [alpha]phase. Sensitivity tests of coupled model on the particular values parameters changing were made. On these basis it was determined the relations of CET (columnar-to-equaiaxed transition) zone position influence. The example of virtual structure validation based on real structure with CET zone location and grain size was shown.
