In order to fulfil the high-speed numerical simulation of casting solidification processes

the Dynamic Boundary Condition Calculation is proposed first time. On the basis of the Similitude Theory in the heat transfer

the authors put forward the Biot Criterion Amendment Formulae. The experiments show that comparing with the traditional simulation methods

it is able to have the used computer storage and time cut down by 60

8

0%

and the relative error of the calculated solidification time is only 3.69%.
