Simulation apparatus, simulation method and non-transitory computer-readable medium having simulation program for fluid-flow analysis of material in kneading device

A simulating method executed by a simulation apparatus for performing a fluid-flow analysis of material and for displaying a graphical user interface (GUI), the method comprising:

• displaying, on the GUI, shape data showing a screw shape relating to an arithmetic object field of a kneading device;
• performing a low-dimensional fluid-flow analysis of the material in the arithmetic object field, based on setting information, the setting information including:
• physical property of the material;
• and
• configuration data and an operation condition of the kneading device for kneading the material;
• receiving, after or before the performing of the low-dimensional fluid-flow analysis, selection of an object area as an object of a high-dimensional fluid-flow analysis in the arithmetic object field, the selection of the object area being an area selected on the shape data displayed on the GUI;
• extracting physical quantities of the material relating to the object area, from among at least two physical quantities obtained from a result of the low-dimensional fluid-flow analysis;
• performing a high-dimensional fluid-flow analysis of the material in the object area, based on the extracted physical quantities and the setting information, wherein at least two of the extracted physical quantities are set as boundary conditions for the high-dimensional fluid-flow analysis;
• and
• displaying, on the GUI, an analysis result of the low-dimensional fluid-flow analysis and an analysis result of the high-dimensional fluid-flow analysis,
• wherein after the performing of the high-dimensional fluid-flow analysis, in response to receiving a selection of a position on the shape data according to an operation of a user, displaying, on the GUI, the analysis result of the low-dimensional fluid-flow analysis of a section in the arithmetic object field, corresponding to the selected position on the shape data, correspondingly with the analysis result of the high-dimensional fluid-flow analysis.
