Verification of an interaction model of an ultrasonic oscillatory system with periodontal tissues
Verification of an interaction model of an ultrasonic oscillatory system with biological tissues which was developed in COMSOL Multiphysics was carried out. It was shown that calculation results in COMSOL Multiphysics obtained using the “Finer” grid (the ratio of the grid step to a minimum transvers...
