Abstract When a body moves in a continuously stratified fluid at a constant speed, the wave field moves along with the body and forms a field of so-called attached internal waves. The incident flow is usually assumed to be constant, and nonstationary waves generated at the initial stage of motion are neglected. In this case, the body is simulated by point-mass sources and the wave field is found using
