Method of creating head model, drive waveform creation method, information processing apparatus, and program

Abstract

A method of creating a head model that can accurately simulate behavior of a liquid ejection head, a drive waveform creation method of creating a proper drive waveform using the head model, and an information processing apparatus and a program for executing the methods are provided. Provided is a method of creating a head model that simulates behavior of a liquid ejection head including a piezoelectric element, the head model being configured using a fluid analysis model, the method including, via one or more first processors, optimizing the head model based on learning data using data related to an actual flight shape in a case of ejecting liquid by applying each of a plurality of drive waveforms to the piezoelectric element using the liquid ejection head and the liquid ejected from the liquid ejection head as the learning data.
