Abstract
A numerical analysis device executes: Step 102 of selecting a fluidic device model and a pipe model used for transient analysis from among fluidic device models and pipe models that are located between a start point and an end point set in the pipeline network model constructed as a 3D model of a pipeline network that includes fluidic devices and pipes; Step 104 of dividing the selected fluidic device model and pipe model into volume elements and into junction elements; Step 106 of deriving volumes of the respective volume elements obtained and pressure loss coefficients corresponding to the respective junction elements, based on the shape of the fluidic device model, a shape of the pipe model, and a physical quantities of the fluid, of associating the volumes with the volume elements, and of associating the pressure loss coefficients with the junction elements.
