Physical quantity simulation method and physical quantity simulation program

摘要

PROBLEM TO BE SOLVED: To provide a physical quantity simulation method capable of reducing a calculation load of a computer while enabling simulation by a two-dimensional analysis model when analyzing three-dimensional behavior. A physical quantity simulation method analyzes the three-dimensional behavior of a particle with respect to a structure by using a plurality of interpolation functions extended to a cylindrical coordinate system as an interpolation function for associating a physical space with a calculation space. do. The physical quantity simulation method is two-dimensional defined by the z-axis and r-axis of the cylindrical coordinate system when the central axis of the structure is the z-axis of the cylindrical coordinate system and the axis orthogonal to the central axis is the r-axis of the cylindrical coordinate system. A particle model with a highly granular interpolation function is placed in the first region where the change in particles is large, and an element with a highly continuous interpolation function is placed in the second region where the change in particles is small. A model is placed to create an analysis model, and simulation is performed based on the analysis model. [Selection diagram] Fig. 3
