Selection device, simulation device, and communication control device

Abstract

The present invention reduces position data to a quantity which can be processed in physical simulation, to thereby stabilize processing time of the physical simulation and prevent a loss of a real-time property. Provided is a selection device for selecting position data indicating a path of a movable part included in an industrial machine when executing physical simulation that treats the movable part as an observation target, the selection device comprising: a holding unit that holds the position data in association with time-series information; a range determination unit that determines a lower limit time and an upper limit time indicating a range for the position data from among the position data held by the holding unit; a number-of-pieces-of-data determination unit that determines the number of pieces of position data to be selected from among the position data in the range in consideration of a processing load of the physical simulation; and a selection unit that selects the set number of pieces of position data from among the position data in the range.
