Fourier's partial differential equation of heat conduction is solved by means of the modified Brian's implicit finite-differences method. The method enables an easier treatment of the boundary conditions and reduces the time of operationalisation of the mathematical model. The thermophysical properties of the materials in the system casting-mould depend on the temperature, which gives nonlinearity to the model. A computer program was written in ASCII FORTRAN and solved on a SPERRY 1106 computer. On the basis of a numerical simulation of the solidification in silica-sand moulds a new formula for the feeding distance as a function of bar thickness is obtained. The results are in relatively good agreement with experimental values from the literature"},{"@xml:lang":"sl","#text":"Razvit je bil tridimenzijski matematični model za strjevanje jeklenih palic v formi iz silikatnega peska. Fourierova parcialna diferencialna enačba za toplotno prevodnost je bila rešena z modificirano Brianovo implicitno metodo končnih elementov. Metoda olajša obravnavo robnih pogojev in skrajša čas operacije matematičnega modela. Termofizikalne lastnosti materialov sistema litja so odvisne od temperature, zato je model nelinearen. Računalniški program je bil napisan v ASCII Fortran in izračunan na računalniku SPERRY 1106. na osnovi numerične simulacije strjevanja je bila v formi iz silikatnega peska razvita nova odvisnost med razdaljo napajanja in debelino jeklene palice.
