Neutron escape probabilities in 3-D reentrant geometries computed using ray tracing

The ray tracing of three-dimensional complex media is the forward simulation technology,being wide application in the practical production nowadays.This paper constructs the complex three-dimensional geological body and interface with the modeling method of block structure and the triangle face,respectively.It uses the test-fire method as the basic arithmetic of the ray tracing to deduce the optimized arithmetic of the ray tracing,speeding up the ray tracing.In the test-fire process,it introduces the basic idea of clustering to increase test-fire density to promote the ray tracing efficiency.In order to obtain the slick and continuous stratum curving face,the constringency precision of the three-dimensional ray tracing is improved by adopting the linear method based on azimuth angle to make the curving face smooth and make sure the rapid ray tracing of the complex modeling.The outcome of the ray tracing of the real geological model proves the improved ray tracing method can enhance the ray tracing speed of complex three-dimensional geological model.
