Heat is generated by friction between the pad and the disk. The simulation assumes that all of the energy dissipated by friction turns into heat. The part of the brake pad away from the disk is restrained in the nonaxial degrees of freedom and is loaded with an axial pressure. The disk is rotated by prescribing its angular velocity over two complete revolutions. Half-symmetry is exploited.
