摘要

The development of ultrasound oscillatory systems for vascular surgery is associated with a number of technological difficulties. This paper compares results from finite element modeling of an ultrasound oscillatory system for treating subcutaneous veins of the lower limbs run in ANSYS and COMSOL Multiphysics with a manufactured model of the system. The modeling error was found to be no greater than 3% for determination of the resonant frequency but could reach 43% for oscillation amplitude.

The accuracy of determining the output characteristics in COMSOL Multiphysics was greater than that in ANSYS.
