【Abstract】 Aiming at the realisation of remote monitoring 3D temperature field distribution of the crystal furnace in materials science experiments so that to easily modify the experimental parameters in time during the process of the experiments,a visualised simulation method for 3D temperature field of crystal furnace is presented.The furnace is modelled with thermodynamics and the discrete solution of the temperature field is derived by numerical method.The incremental insertion is employed to conduct the tetrahedron division of the discrete solution obtained,the contour line and isosurface are drawn,and then OpenInventor is used as the 3D visualisation platform to depict the distribution of the temperature field in heart of the furnace.All these provide intuitive basis to material scientists on studying the processing course of material samples,and help them to control the technological process of the experiments.The validity and feasibility of this approach is demonstrated through experiments.更多还原
