In this work authors showed results of simulation manufacturing closed skeleton casting. The aim of conducted simulations was the choice of thermal and geometrical parameters for the needs of designed calculations of the skeleton castings and the estimation of the guidelines for the technology of manufacturing. During simulation effect at mould filling process for the skeleton casting was analyzed. Analysis of temperature distribution and analysis of solidification closed aluminium skeleton casting were conduced. It was confirmed that the metal is flows at the external surfaces and fills internal channels of skeleton, until the moment of overall filling of the mould. Whole casting is solidification in finish of pouring mould. It is advantageous by reasons of satisfactory mould filling. Part of casting which was connected with feeder, on upper surface of casting solidified the slowest. in consequence to the lowest heat give up.
